Assistance Researcher **Gernica**: According to the direct demand of the Overseer Council, you have been granted all the clearance to access the secret file database of the Foundation. The clearance will expire in seven days.

The Overseer Council wants you to investigate an unknown anomaly **##red|SCP-CN-3969##**, and summarize a detailed description and investigation report. The artificially intelligent conscript  **##4c4cff|Tidal.AIC##** will assist you to proceed this task. This anomaly seems to have a connection with a megaproject the Foundation has built, but all related documents were lost, the reason is unknown. Due to the nature of the task, we can't offer more people to help.

Other information will be provided by Tidal.AIC.

I'm trying to organize words to express my shock when receiving the message above.

Let me introduce myself, I, Dr. Gernica, just finished my training three months ago. Now I'm helping my mentor with a theoretical research project in the shabby site located in nowhere. I just finished my dinner when the phone rang, and it took me twenty minutes and five verification codes to open this email. Then, I saw the message contained fewer than two hundred words, and the sender was the Overseer Council.

I just checked that, the SCP list, which contains thousands of lines, and all the "[Insufficient Clearance]" are turned into Item Numbers. I can just read anything like reading some kind of online novels.

What the [REDACTED]?

Okay. First, SCP-CN-3969 is a very special anomaly, the Foundation's confidentiality regulation requires the investigation into this kind of anomaly must be conducted by only one person. What's more, due to the abnormal nature of this item, traditional investigation methods, such as assembling a special team, are unlikely to work. All in all, this task can only be finished by you.

For the latter requirement from you, sorry I can't obey, because I also have no power to contact the Overseer Council; Only when the investigation is finished, I can send the report to them.

**Item #:** SCP-CN-3969

**Object Class:** Pending/Thaumiel

**Special Containment Procedures:** Not available at present. The **##20B2AA|Gemini Class## investigation** on SCP-CN-3969 has already started. After the investigation is finished, SCP-CN-3969 will be assigned with an Object Class, and the Containment Procedures will be created.

**Description:** SCP-CN-3969 is a giant engineering and scientific research project started by the Foundation in the 1950s, CODE NAME: "##red|**PROJECT UDEM**##".

The original files of SCP-CN-3969 and Project UDEM were mostly lost. The reason is unknown, but it is certain that this was some cover-up measure of intention. Due to the unavailability of the exact list of people related to Project UDEM, and its confidentiality procedures contain a special information erasure mechanism, investigating SCP-CN-3969 by a normal method is considered impossible.

]]

In the initial stage, when investigating SCP-CN-3969 in the normal way, the documents and data related to SCP-CN-3969 were found to have cognitive hazard or antimemetic effects. Later experiments shows, the effects of information about SCP-CN-3969 seems [[[SCP-3930|positively correlated with the number of cognizers.]]]: The more people are aware of SCP-CN-3969, its antimemetic effects will be stronger; Conversely, in a situation where there's little cognizer of SCP-CN-3969, its antimemetic effects fade, and it no longer poses a cognitive hazard.

Because of that, the Gemini Class investigation was specially founded, its aim is to improve information fidelity by controlling the number of investigators. The task will have results in several days.

Although there is no formal documentation, the existence of Project UDEM can still be inferred from numerous discrete documents or materials[[footnote]] Despite this, much information still contradicts itself. The information mentioned below is the part that was verified to have no contradiction.  [[/footnote]]. At this moment, the information that is known and has high credibility includes:

* Multiple foundation departments has participated in this project, among them the main departments were the Department of Physics (mainly the Department of Nuclear Physics and Department of Quantum Physics), the Engineering Department and the Department of [[span class="ruby"]]E.O.W[[span class="rt"]]END OF THE WORLD[[/span]][[/span]]
* Project UDEM seems to be trying to build a large-scale equipment/structure/building, whose direct aim was to replace [[[SCP-2000]]].
* Like other important projects like SCP-2000, the Overseer Council can directly decide on important matters on this project.[[footnote]] This also partly explained why Project UDEM has abnormal classification levels. [[/footnote]]
* It should be noticed that the final product of Project UDEM, aka **SCP-CN-3969-Thaumiel**, seems already finished/very close to finish, but due to some kind of abnormal effects/human damage, Project UDEM was stopped in such a short time, and the participants received amnesia.

As the replacement of SCP-2000, the importance of SCP-CN-3969-Thaumiel (or the product of Project UDEM) is needless to say. So, an unconventional investigation on SCP-CN-3969 is necessary.

I already found some information related to SCP-CN-3969. This information was buried in the Foundation's deep databases and hard to find by conventional methods. And just like the description says, their antimemetic effects are very strong, and you almost can't remember anything without injecting Mnestics.

You can first check out these barely decent files, I will try to clean out other files' antimemes and cognitive hazards.

++ Part 3: The Instability

[[include :scp-wiki-cn:component:image-block-peppo

|caption=July 1949, above SCP-2000 Core Replication Zone during [REDACTED] activity. The function of SCP-2000 had fully restored after six months.
|width=100%
]]

As an underground facility built in the early twentieth century, the designed life of SCP-2000 (1000 years) has been proven unattainable. At the most optimistic estimate made by the Yellowstone Project, SCP-2000 would be totally inoperable within 50 to 100 years. Even now, the function test on it has met some obstacles, the core subsystem Bright/Zartion Hominid Replicators have already failed to improve the accuracy of gene replication to 97%^^[39-40]^^. The SRA array's mean time between failures has also fallen to 1990 hours (average value).

It is obvious that the instability of SCP-2000 became more critical in recent years, especially after the activity of [REDACTED] in July 1949. We can make sure that in several years ahead, Yellowstone can't be used as a reliable failsafe for human civilization. On the opposite, if SCP-2000 is not completely repaired, its instability can even become a potential hazard. For example, the global disaster monitor system of SCP-2000 has already reported several false alarms. Although it hasn't led to more fatal self-operating, it is still a huge danger alarm.

I want the Overseer Council to put further notice: Despite the instability caused by engineering and technological issues, the SCP-2000 has another great, and more complex instability, which is the core principle of SCP-2000.

I don't want to discuss complex problems like the paradox of the ship of Theseus, however, the current performance of SCP-2000 can't persuade us to trust the principle—— replicate humans on a large scale and rebuild the world—— would work. In normal situations, the reliability of SCP-2000 can ensure it saves the world in such an indirect way, but the problem is: It is not reliable.

The work of investigating the feasibility of the underlying principles of SCP-2000 has already started. For now, most people of Project Yellowstone think the root of the problems of SCP-2000 is its working principle. After all, it is too indirect and unstable. The task of rebuilding the world is in the hands of a group of clones, and no one would know what would happen. Dr. Christopher Zartion MD warned us at the end of the report of the 126th maintenance cycle of SCP-2000: the lifespan of SCP-2000 might be shorter than we think.

Now let's focus on the series of accidents of SCP-2000 that happened in July...

**Abstract:** Several days later, after the administrator of Project Yellowstone **William Fritz** released the files above, SCP-2000 had another critical malfunction. Among the twenty-three subsystems, seventeen were already unable to operate properly. The repair of SCP-2000 had been raised to the A-Class emergency of the Foundation, and the Project Yellowstone Full emergency Summit was immediately called.

After the summit, William Fritz submitted the file below to the **##red|Overseer Council##**. The file is considered the key that persuaded the Overseer Council to start the Project UDEM. The whole file is presented below:

Overseer Council:

[[div class="tid"]]

You have heard about the accident of SCP-2000 recently. The Yellowstone Project administration has known the operational status of the few remaining subsystems we have through the recent work of Dr. Thaddeus Xyank. The situation is far from optimistic. In fact, we have to make the most pessimistic prediction: SCP-2000 won't be disabled in fifty years or later, instead, it will be disabled in just a few years in the near future.

Based on that, someone may think that we should build a new SCP-2000. However, this idea is assessed, and it won't work. Because the intrinsic reason for SCP-2000's poor performance is not our engineering technology's flaw (Although we must admit that many flaws in SCP-2000's design can be prevented), but its fundamental principle. SCP-2000 itself is a fragile Doomsday facility, although we have confidence in evading nuclear bombs or antimatter, it is still not a doomsday failsafe that is good enough.

The assumptions above are based on the following truth:

1. Among the possible doomsday scenarios the Department of E.O.W put forward, 75% of them relate to hyper-scientific elements like extraterrestrial civilizations[[footnote]] ADK-Class "Complete Anomalous Destabilization" Scenario or SK-Class Dominance Shift Scenario can describe this kind of situation. The former one applies to the extraterrestrial civilizations that use anomaly measure. [[/footnote]], Divine Beings, Pataphysics, Thaumaturgy, and Physics that are beyond current understanding. Doomsday scenario caused by one or multiple of them won't be coped with by SCP-2000.

2. Even though the Doomsday Scenarios that can be explained by current theories, there are also elements that are hard to deal with like celestial impact and supernatural bio-hazard. Doomsday scenarios caused by these kinds of elements can be dealed on some degree, but the chance of civilization's survival is remote.

3. From the current situation of the Foundation, the resources needed to build another SCP-2000 would lead to a series of problems out of control, and the engineering cycle is far longer than repairing the original SCP-2000, the "Doomsday void[[footnote]] A period that has no doomsday failsafe. In this situation, any K-Class Scenario would heavily threaten civilization's survival. [[/footnote]] would be inevitable.

The administration advises that, start a new engineering project by the Foundation, exploring the possibility of setting up a totally stable and absolutely reliable doomsday failsafe, which is the "**##FFD700|Ultimate Deus Ex Machina##**"(UDEM) Project put forward by the Department of E.O.W, and completely replace SCP-2000 with it. In the DOEOW's opinion, although the Foundation may have no capacity to build UDEM, the new failsafe whose aim was UDEM would improve the awkward situation SCP-2000 has brought to us.

I recently acknowledged that the Global Occult Coalition has planned to conduct new nuclear tests. Considering the unstable elements gradually piled up in the environment, perhaps the Council should decide related things as soon as possible, and assign people to do the preliminary work.

After the file reached the Overseer Council, an overseer general assembly is held immediately to decide on the proposal of building UDEM, aka "Ultimate Deus Ex Machina". The #2280 proposal put forward by O5-1 was unanimously approved.

It is widely considered that September 1st, 1950, was the beginning of Project UDEM.

In fact, the O5 Council approved the proposal together had already demonstrated UDEM's significance to the Foundation at that time. From this point forward, we can find relevant information more easily. I have already found some scattered meeting records and engineering documents, but I think what you need are some more general files, like project plans.

Considering possible cognitive hazards, you should ask your site administrator for Mnestics and memetic vaccines.

Is there any possibility that... The anomaly nature of these files is the clue? What do you think?

You made a valid point. After all, conventional encryption is enough for most confidential information. Although every time I finish a task, a huge part of my memory would be erased, I can still tell you that among the information I know, there are no previous examples that the Foundation intentionally attaches information hazards to its own databases.

**Abstract:** The Project UDEM started preliminary research in September 1950. Twenty-seven Research departments, including the Department of Physics, Astronomy, Quantum Mechanics, Thaumaturgy, and the Department of E.O.W have initiated to study UDEM's feasibility. Several months later, the research proposals were compiled at Site-62, but the final plan had yet to be determined. Under the order of the Overseer Council, a Sub-summit (O4 Council) was called to determine the final research direction.

**Introduction:** The proposal of building "Ultimate Deus Ex Machina", aka UDEM, was put forward by the Overseer Council several months ago.

After months of theoretical research, it is now considered that UDEM is possible in theory. But on the theoretical approach, differences emerged. The mainstream views fall into two categories: Participants, which mainly consist of physicists, including William Fritz, think the Foundation must develop the fundamental theory of Quantum Physics, and build the UDEM device based on modern physics, and the researchers of Thaumaturgy think the UDEM should be based on Thaumaturgy and Tactical Theology.

The aim of the summit is to completely decide the technology route of UDEM.

**List of Participants:**
* **Overseer Council members:** O5-1, -2, -12
* Dr. William Fritz(Leader of the Summit)[[footnote]] The Administrator of Yellowstone administration, also the leader of DOEOW [[/footnote]]
* Administrator Scott Nathaniei[[footnote]] The Administrator of Site-62 [[/footnote]]

> Video record started. Inside the conference room of Site-62.

[[span class="name"]]**Dr. William Fritz**[[/span]]
Has the record started? Good, I'll get straight to the point: I think we should deal with the problem as soon as possible. These weeks, I, and you //(Looking at the participants of the Department of Physics)// would thank god for sleeping for four hours.

[[span class="name"]]**Administrator Scott Nathaniei**[[/span]]
I believe this summit can resolve your theoretical conflicts. At the same time I also appreciate that the Overseer Council could come to this summit, but considering that we don't have much time—According to Fritz—maybe most people would like to get straight to the agenda as soon as possible. According to the usual practice, Fritz, can you report what conflict Project UDEM has?

[[span class="name"]]**Dr. William Fritz**[[/span]]
Okay. //(Looking through the documents)// As we are all familiar with, the hardship of preliminary theoretical works is to decide the research direction.

Now we have two directions, one is insisted by the Department of Physics—Proceed with the fundamental physics research first, including basic institute development of particle physics, and later put into application. The other is the proposal of the Department of Thaumaturgy and the Department of Tactical Theology, they think UDEM can't be built without anomaly theories, so building thaumaturgy and theology institutes will be the next step of the plan.

The two directions, after the evaluation of the Department of Finance, the investment needs for both are astronomical. The Foundation can't pursue both at the same time, so the research route must be decided as soon as possible, and finish the whole project before the "Doomsday Void" falls on us—— which means to finish the whole project in ten years.

> After the speech ended, the whole conference room was silent for a short time.

[[span class="name"]]**Administrator Scott Nathaniei**[[/span]]
Er, Fedorov, who will speak first? You or Wood? 

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
I'll go first. We all know that the Foundation's progress on physics is ahead of those outside the Veil for about fifty years, and the greatest outcome in the past decade is to describe quantum gravity successfully by the partial proof of AdS/CFT correspondence[[footnote]] The relationship of Anti-de Sitter space(AdS) and Conformal Field Theory(CFT). The Foundation described the theory of the Holographic principle. Reference: [https://www.qiuwenbaike.cn/wiki/AdS/CFT%E5%AF%B9%E5%81%B6 AdS/CFT对偶] [[/footnote]], and implemented ToE indirectly by that.

However, there is still a contradiction unsolved between quantum mechanics and general relativity, which is: AdS/CFT correspondence still allows quantum mechanics to violate Bell's inequality, which totally contradicts general relativity, because this still means superluminal information transmission is possible, and even possible on a macroscopic level. A series of experiments conducted in 1946 verified this result.

In recent years' theoretical research the Department of Physics has gradually found this paradox, which is the quantum superluminal problem in any means gradually become the, er, in a classical term, "Two clouds on the towering building of physics". If we want to achieve the perfect all-theory, we have to come up with methods to explain this.

> Fedorov's deep russian accent made the listeners found that he was speaking English when he had already finished half of the speech. Dr.Sherwood showed impatience and cut Fedorov's speech when he was taking a pause.

[[span class="name"]]**Dr. Webster Sherwood**[[/span]]
Sorry to interrupt, Dr. Fedorov. Does this relate to UDEM?

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
I was about to talk about this. The people who have read popular science books know that: the relativity predicts that superluminal must lead to time reversal, and then we encounter old problems like grandfather paradox and butterfly effects, but recent research of the Department of Physics, especially some subfields in Soviet sites is rather evolutionary. Some research conducted on high-energy physics facilities in Area-RU-21 in Moscow overturned some conclusions of ToE, including some sub-atomic superluminal effects.

Let's talk back to your UDEM. The essence of UDEM is to consistently cope with everything without changing, avoiding any E.O.W from its origin with complete certainty. That means our approach can't be passively "defending" us from K-Class scenarios, but to attack actively. If we can cut off all the origins of K-Class, it would be nice.

[[span class="name"]]**Dr. William Fritz**[[/span]]
That's the point. I agree with you, but how could physics help us to achieve this feat?

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Don't rush, I'm going to talk about this soon. Fritz, after getting the exact requirements of Project UDEM, we had some discussion with your DOEOW. Just like what we talked about several days ago, K-Class Scenarios need some critical "factors" to happen, and what makes me interested is that the relations of the factors can be described mathematically in theory.

[[span class="name"]]**Dr. William Fritz**[[/span]]
Yes, that's also the fundamental concept of eschatology. But creating a mathematical possibility model for K-Class Scenarios needs a strict requirement, just the computing power alone is hard to quantify.

[[span class="name"]]**Dr. Christopher Zartion**[[/span]]
But if I remember correctly, DOEOW already has some basic models, right? Oh, sorry for the interruption.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Yes, it's what they called "eschatology based on number theory". Put it simply: The factors caused E.O.W, or in eschatology terms——E.O.W factors, in the simplest description, they can be expressed by a set of vectors in high-dimensional, possibility-describing Hilbert space. To turn this into practical research, we need to solve two problems: First, how to verify or detect E.O.W factors, which is to measure its specific parameters. Second, how to change E.O.W factors, which is to change the parameters.

[[span class="name"]]**Dr. William Fritz**[[/span]]
Yes, if we only know a few parameters of the E.O.W factors, the model can only predict the general probability of the happening of K-Class Scenarios. But as the accuracy of the model improves, the result we are getting become clearer, to the extent that something will happen in which year.

[[span class="name"]]**Dr. Webster Sherwood**[[/span]]
You have talked about this theory predicts when the K-Class Scenario would happen, or how to happen, but what we need is to eliminate the E.O.W factors.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
"Eliminate" E.O.W factors, in fact, is to make the factors to orthogomal to the Universe's coordinate axis—by this way, the projection of E.O.W factors on axis became a zero vector, in simple terms, their impact on our Universe is zero.

[[span class="name"]]**Dr. Webster Sherwood**[[/span]]
Then how can we change the parameters you talked about? 

> After this sentence finished, Dr. Webster Sherwood didn't get the answer in nearly a minute. Fedorov talked nothing, glazing the conference hall slowly, and absently flipping through the papers and folders on the table from time to time. Finally, before someone became impatient and broke the silence, Prokopiy Fedorov opened his mouth:

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
That's the problem. How can we change it? How to change the fate of our universe by using pure physical methods? Did anyone think about the possibility before? 

Our civilization is a chaotic system, any tiny disturbance can cause the prediction of the future became unreliable, not to mention directed interference. In this situation, how do we prevent doomsday events from happening in the beginning? If the event that caused doomsday to happen is decided before human existence, then how can we reverse it? Do you, even the Department of Thaumaturgy or DOEOW, have ever considered how hard it is? 

I've read the files of the Department of Thaumaturgy, their proposal was to get a Divine Being, whether to pray for one or build one by themselves, using 50% GDP of the whole world, cause the veil to broke and collaborate with the most GoI we have known. Speaking in an impolite way, I deeply despise this proposal. We want the UDEM to ensure the permanent existence of humanity, but we built it upon a non-human basis, this is a great irony to us.

> Fedorov's speech truly dropped a bombshell. After a deadly silence, Dr. Sherwood glanced around at the surrounding members and decided to stand up to contradict him on his own.

[[span class="name"]]**Dr. Webster Sherwood**[[/span]]
Fedorov, I am extremely disappointed by your empty talks. I don't know whether you are affected by the atheism propaganda of the Soviet, but your basic mistake is simply laughable. I will ask you now, why do you think your physics can do better than us? If you are capable, show us your proposal.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
You think I don't have a proposal? Of course I have.

> Fedorov pulled out an oversized suitcase under the desk. He opened the suitcase and took out a huge pile of folders from the case. This surprising reply made the participants look at each other in surprise. Fedorov took the folder on top:

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
In February 1949, the Department of Physics held a secret academic discussion based on a new theory, which was reverse deducted by the results from Area-RU-21. That was basically a wildly imaginative brainstorm, but coincidentally, our topics indeed have something similar to UDEM, the other files are still classified and stored as a theoretical foundation.

The code name of that subject is **"##0000CD|Mortise-Tenon##"**. It described a theoretically possible decoherent histories guiding system. Put simply, we can orientally decide past histories almost at will. After we received the requirements of UDEM, we quickly reviewed the subject, and reached the conclusion: It works.

[[span class="name"]]**Dr. Webster Sherwood**[[/span]]
…So, what's that new theory?

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
To decide past histories, as what we know, there's only one method.

> The conference hall became silent again, this time the silence became longer than any other, everyone knew there's only one answer, but no one dared to speak, because it was so ridiculous.

I have already read several documents, and still have no clue.

Tidal.AIC claims that "I also don't know why you're chosen, perhaps you have some special gifts, like getting a full score in memory tests when being assessed". Honest speaking, I really don't know how to investigate this thing.

The drugs of cognitive hazards protection are within my reach. After eating this, my head hurts, but without this thing, my head would be more hurt possibly. I've really had enough.

**To Dr. Fedorov:**

The Department of Physics won. The Overseers' instruction mentioned "Don't want UDEM to have thaumaturgy parts" specifically. You and your scruffy Soviets won the bid.
I don't have anything more to say. Hope the Foundation will get your brilliant ideas done. Wish you good luck.

**Abstract:**After the held of Site-62 Sub-summit, the Overseer Council adopted the "Mortise-Tenon" proposal of the Department of Physics by a large majority with 10 votes in favor and 3 absentions, The Project UDEM entered the stage of theoretical verification and feasibility study. The task was soon finished under the leadership of Dr. Prokopiy Fedorov. The Engineering Department joined the UDEM department protocol and started choosing the site and early-stage construction.

Qinghai, em…and Nevada. The files I've found were basically about these two places, all were some kind of task reports. We can see that the Foundation's classification works are pretty good, after hundreds of pages I still have no idea of what they were doing. Building accelerators? What's the point? It caused my head to hurt more…

UDEM now has a more formal code name—Project No.634. It doesn't feel like the name chosen by the Foundation.

Other clues… nuclear physicists, and pioneering physicists were almost being moved to a mysterious base in Nevada. On satellite images, there's just a desert, it was torn down completely. The Berkeley Lab's scientists were all moved, especially the professionals of nuclear physics—the one who has the highest ranking is Seaborg (Glenn Theodore Seaborg), who is the great one in the field of superheavy elements, he seems to have a direct meeting with the Overseers.

Of course there are some design blueprints, although I don't understand… Well, in all means, they are more likely building a bomb instead of building some machina.

**Overseer Council:**

Recently we have had a little obstacle in our wor,ks.

We underestimated the complexity of Project No.634, of course the problem isn't so severe that we can't push the task forward, but the Department of Physics expressed that they're lacking hands. Fedorov told me that we should try our best to get more potential pioneering physicists. Perhaps he hasn't realized that the academic team that participated in Project 634 is already pretty big, hiring more people can even affect the stability of the veil.

And, Dr. Christopher Zartion told me that we need to consider letting the Aerospace Department to participate. After I discussed this with Fedorov, due to the nature of AN-███.1, the DOEOW confirmed that it is necessary. Without doubt, this would cause the resource demand of Project 634 to have a further increase.

The detailed report will be sent in a couple of minutes. As the possible most important project of the Foundation in this century, I sincerely hope the Overseers would give Project No.634 a higher priority.

Christopher Zartion? The leader of the department of bio-whatever?

[[div class="blockquote u-1"]]
Yes. Dr. Christopher Zartion is the leader of the Department of Research and Development of bio-technology, he participated in the design of early versions of Bright/Zartion Hominid Replicator. It is unsurprising for him to appear as one of the managers of Project No.634.
[[/div]]


[[div class="blockquote u-2"]]
But why did he propose to let the Aerospace Department participate in Project 634—— and the whole Project No.634 doesn't seem to have anything related to biology.
[[/div]]


[[div class="blockquote u-1"]]
Dr. Christopher Zartion has a great contribution in the construction and maintenance of SCP-2000, his research areas are also not limited to biology. We can say that, apart from William, he's the only one who knows SCP-2000 best. Obviously, he could avoid the product of Project No.634, which is UDEM(SCP-CN-3969-Thaumiel), to have critical flaws like SCP-2000.
[[/div]]


[[div class="blockquote u-2"]]
Is he planning to move the entire device into space? 
[[/div]]


[[div class="blockquote u-1"]]
We cannot rule out this possibility. And, I found the records of the Sub-summit the Overseer Council mentioned. It should solve some of your questions on Project No.634.

**Note:**

This file transcribes the first meeting of the Sub-summit.

This summit aims to decide the methods to deal with the critical problems:
1. The problem of the trial explosion of AN-███.1: Due to the immense power of heavy fusion bombs, it has long been considered impossible to conduct surface nuclear tests. There were several ideas on how to verify the feasibility of the configuration of AN-███.1.Since the first experimental bomb of AN-███.1 will be finished soon, the summit must decide its test detonation method.
2. The deployment of UDEM system. Since the UDEM is a one-time system, its deployment methods, including construction, maintenance and, trigger, must be valid in extreme conditions.
3. Other conventional problems, including agendas like the specific design of traceable quantum keys and the maintenance of the Nevada High-Energy Physics Research Facility, will be solved in a series of small-scale meetings at the secondary summits.

[[span class="name"]]**Dr. William Fritz**[[/span]]
But what we are discussing is the power of AN-███ itself, Dr. Moore. If you insist on conducting underground tests, we need to consider this thing used the whole crust as its fusion fuel.

[[span class="name"]]**Dr. Xenia Moore**[[/span]]
The critical is the detonation temperature we calculated, Firtz. You also admit that the temperature could possibly burn out the whole atmosphere, but unlikely to let silicon or aluminum to fuse… Dunn, what's your idea? 

[[span class="name"]]**Duke Dunn Patience**[[/span]]
The calculation result from the prototype of supercomputer AK9MKII shows that, the safety of underground nuclear tests is generally adequate. If we denote this in space it would have the possibility to disable half of the satellites and electronic devices on surfacethe , for other test grounds… We can't conduct a heavy nuclear explosion under the sea, right? 

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Of course we have "other test grounds", Dunn. Wouldn't deep space or the lunar surface work?

[[span class="name"]]**Duke Dunn Patience**[[/span]]
Astronomical telescopes around the world would be able to see this nuclear fireball, which is brighter than the full moon, doctor. And the Foundation doesn't have a rocket with a 200-ton LTO payload capacity, EMTP-1 is still under construction at this time, and it can only launch one-tenth of the AN-███.1 payload into orbit.

[[span class="name"]]**Dr. William Fritz**[[/span]]
In fact I also considered conducting the trial on the surface of another planet… But the dramatic demand for payload capacity makes this idea impossible.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Such rockets exist, Fritz. As I know, the Ganzir fortress city of GOC has a port that meets the requirements of a ten-thousand-ton class rocket——

[[span class="name"]]**Dr. William Fritz**[[/span]]
Wait, how much did you just say? 

[[span class="name"]]**Liaison Laurel Foster**[[/span]]
What he says is true. Recent operations of GOC exposed some traces of Ganzir. Our satellite shows… er, it has been expanded significantly compared to before. What's more, there are two SHLV prototypes. The estimated diameter of the rocket body is approximately 35 meters, with a mass of 12,000 tons, and its LEO payload capacity is estimated to exceed 1,000 tons.

[[span class="name"]]**Dr. William Fritz**[[/span]]
This sounds like mythology. Do we have more information?

[[span class="name"]]**Liaison Laurel Foster**[[/span]]
No, but if you want, obviously we can negotiate with GOC for cooperation, we have precedents.

> (Silence)

[[span class="name"]]**Dr. William Fritz**[[/span]]
This would need to be reported to the Overseer Council.

[[div class="blockquote u-2"]]
That's——so——long——
[[/div]]

[[div class="blockquote u-1"]]
But it is some critical information. The dialogues in several minutes at least exposed part of UDEM, for example, the heavy-fusion bomb AN-███.1 seems to be an important part of UDEM.
[[/div]]

[[div class="blockquote u-2"]]
My major wasn't nuclear physics. I can't understand those things!
[[/div]]

[[div class="blockquote u-1"]]
Do you know the basic principle of atomic bombs? The nuclear fission chain reaction caused energy release that is uncontrollable, and the hydrogen bomb uses a fission bomb as the nuclear fusion trigger. The fuel materials of nuclear fusion are deuterium and tritium, these two isotopes fuse into helium and release energy, which causes an energy release on a larger scale.
[[/div]]

[[div class="blockquote u-2"]]
I have learned that in Physics class in high school… but what the heck is a heavy-fusion bomb, I remember the binding energy or something else became a minus number starting from iron, so it can't fuse…
[[/div]]

[[div class="blockquote u-1"]]
It can fuse, but the fusion will absorb energy instead of releasing energy. I guess the heavy-fusion bomb partially breaks the limitation, it is possible that it uses a hydrogen bomb as the reaction source to cause the fusion of heavy elements. This kind of fusion is likely to produce extreme heat, although its total energy released has become less, but the destruction would be greater than hydrogen bomb. Of course, this is my conclusion deduced from the records, it may not be correct.
[[/div]]

[[div class="blockquote u-2"]]
Is that considered as popularize science to me?
[[/div]]

[[div class="blockquote u-1"]]
To you, yes.

[[span class="name"]]**Dr. William Fritz**[[/span]]
…We have another topic to discuss—The deploy method.

[[span class="name"]]**Dr. Thaddeus Xyank**[[/span]]
The traceable quantum keys could ensure UDEM won't be triggered maliciously. But considering the carrier's precision, and of course the AN-███.1 itself is pretty precise, the deploy method must be ensured to be safe, completely safe.

[[span class="name"]]**Dr. William Fritz**[[/span]]
(Nod) Even at the end of the world it still needs to be safe…This connects with the purpose of UDEM. Did we make a circular argument? 

[[span class="name"]]**Dr. Christopher Zartion**[[/span]]
In fact, I think that's the easiest thing to ensure, we can just put a 2000 around the whole system. We just need to defend UDEM from disasters directly targeting UDEM like war, earthquake, regional Hume collapse, and CK-Class Restructuring Scenario, these were what 2000 should deal with…

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
And for those disasters that can erase the planet below our feet, as soon as we are going——

[[span class="name"]]**Dr. William Fritz**[[/span]]
(Cut in) Sorry doctor, I know what you want to say, but our response time is unlikely…

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Yeah, so my question is: How to design an activate system that meets these conditions: 1. When we need it it should be activated immediately; 2. When we don't need that it won't start under any conditions, better let everyone forget this thing. I'm not asking it to prevent the disasters that can wipe out the whole universe immediately, in no condition that's our responsibility.

> The conference hall became silent, then a tiny discussion voice started to appear.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Especially when we don't need it, it shouldn't start. The UDEM itself could be a trigger for XK-Class Scenarios, we have discussed that on the last topic.

[[span class="name"]]**Dr. Thaddeus Xyank**[[/span]]
I agree. I noticed that the AN-███.1 actually needs a radioactive source to work, maybe we can consider…

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Minimize the radioactive source? To be honest, this was not easy. I would rather think from the position of AN-███.1 arrays.

[[span class="name"]]**Dr. Christopher Zartion**[[/span]]
Dr.Moore, what's your opinion? 

[[span class="name"]]**Dr. Xenia Moore**[[/span]]
What Dr.Fedorov talks about makes sense. Perhaps we could put those heavy-fusion bombs in near-earth orbit, when we need we could launch the radioactive source to the orbit—— Of course, it was just oral.

[[span class="name"]]**Dr. William Fritz**[[/span]]
After the production line of AN-███.1 started won't just produce one unit or two, after all the most conservative estimate for UDEM is eight units. We have the capacity to set up a UDEM system for every major site.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
…That's not just a bigger version of Alpha nukes. The power of AN-███.1 is not funny.

[[span class="name"]]**Dr. William Fritz**[[/span]]
That can only blame to our proposal being too violent. In fact I think using the key as the trigger is easier than minimizing the radioactive source.

[[span class="name"]]**Dr. Prokopiy Fedorov**[[/span]]
Making the UDEM operable when they are together?

[[span class="name"]]**Dr. Thaddeus Xyank**[[/span]]
They can't be together,  Dr. Fedorov, I don't think at that situation the owner of the key is professional enough to install the key to the device manually.

We need to consider this possibility: The person who is resoposible to activate UDEM is not a personnel of the Foundation, it may be a normal people who is running for his life, when he gets the key he even don't know where to find a Foundation site. At the moment the Foundation is collapsed, its members were massacred, this is even considering there are still people when Doomsday.

We must remember that: UDEM needs to include the possibility of lacking any favorable factors, including its designers.

A lot of O5 were present at the summit. But they don't say many words.

In fact the Overseers, didn't say anything in the first half of the Summit.
[[/div]]

[[div class="blockquote u-2"]]
Yeah, there are other interesting things. Rockets that weigh over ten thousand tons, GOC chose to collaborate with us… and still I don't understand what's the relationship between producing nukes and saving the world. 
[[/div]]

[[div class="blockquote u-1"]]
I have accessed all databases within my capacity, and I really can't reach a reasonable explanation. But I hope you don't think of some conspiracy theories, such as the aim of the Foundation is actually to destroy the world, or the Foundation is doing thaumaturgy engineering secretly, these both can't explain why GOC decided to collaborate.
[[/div]]

[[div class="blockquote u-2"]]
…GOC accepted? They really have carriers that at ten-thousand-ton class?

[[div class="blockquote u-2"]]
What?

[[div class="blockquote u-1"]]
Is that surprising? That's the Fifties, five years later the first man-made satellite would enter orbit, seventeen years later humans could reach the moon, thirty years later we could make space shuttles. The world behind the veil is more advanced in the beginning, even the UDEM can be tried, not to mention aerospace projects based on conventional technology.

I have no doubt that even the people inside the veil have the capacity to build carriers at the same scale, because there are such precedents (remain on paper)[[footnote]]Sea Dragon Rocket[[/footnote]], You need to believe that people can do anything to prove who is superior during the Cold War.

…The negotiation with GOC has successfully ended, and the Coalition has agreed to allow the Foundation to rent its new spaceport based on [REDACTED] treaty. In the afternoon of June 9th, the vessel carrying AN-███.1-K prototype of the Foundation stopped at Ganzir and unload the payload. Five hours later the payload successfully reached the new spaceport, and was successfully installed inside the fairing of "Valkyrie I" SHLV.

The -K prototype additionally installed a deep-space engine system, made it has the capability to soft land on celestial objects with a gravitational less than 0.8g.

[[div class="modal"]]
Information: The "Valkyrie" SHLV has a configuration of two and a half stages, its first and second stages are capable of sea recovery. The "Valkyrie" has a takeoff mass of more than 12 thousand tons, the LEO capacity is 1600 tons, the LTO capacity is 500 tons, the fairing has a diameter of 20 meters and a height of 45 meters, and on the basis of containing AN-███.1-K, it can also take a monitoring satellite and manned landing module.


 [[=image https://scpsandboxcn.wikidot.com/local--files/oxygen9-files/cohaf_11f.png]]



Considering personnel's safety, this test denotation would proceed by program after rocket ignition. No manual intervention will be carried out except for possible emergency stops.
[[/div]]

At 21:22:16 June 9th, "Valkyrie I" ignited. The first stage of "Valkyrie I" is installed with two solid-propellant boosters and 96 "Fury" liquid-propellant rocket engines, sea-level thrust is 14.6 thousand tons, and the thrust-to-weight ratio is 1.2.

T+182s, the boosters shut down and detach. T+338s, the fairing detaches. T+552s, first stage detach. T+740s, The engine of the second stage shuts down. T+1770s, the engine of the second stage ignited again, the second stage structure entered the TLI orbit.

The first and second stage entered the atmosphere, afterwards, opened grid fins and ignited again, landed on the sea around Ganzir.

At 9:29 on June 30th, the payload docked into moon orbit and landed on the far side of the moon 30 minutes later. The monitoring satellite was detached when landing and changed orbit automatically. After landing, parts of the monitor devices detached automatically and retreated to the proposed position. At the same time, the -K prototype sent the "ALL CLEAR" signal, the test denotation would start after the satellite entered the explosion azimuth angle. To ensure the denotation won't be observed by astronomical telescopes, the denotation center was chosen at the center of the Giordano Bruno impact crater on the far side of the moon.

At 18:12:38 July 30th, AN-███.1-K denotates.

The detonation process was conducted entirely in accordance with the designed UDEM activation process. After the key/radioactive source carrier is integrated with the main structure of AN-███.1-K, the atomic bomb on the outer shell was successfully detonated, the deuterium and tritium fusion fuel was activated, successfully caused the chain reaction of heavy fusion fuel. Due to the desire to avoid ██████ effects from happening, the explosive yield of AN-███.1 had been reduced to 45%, but the detonation power still far beyond the estimated value. Later calculations show that four full-power (120% explosive yield) units of AN-███.1 is enough to cause ██████ effect, thus reducing the construction cost of the UDEM.

Within one-thousandth of a second after detonation, AN-███.1-K effectively created a supernova-like structure. Its high-energy radiation severely damaged the monitoring satellite that was operating over the far side of the Moon at that time. All equipment within a radius of 50 kilometers lost contact, and only the equipment that had retreated to 100 kilometers away transmitted sufficient observation data.

The Giordano Bruno impact crater lost its structural feature.

Within one-tenth of a second after detonation, a large amount of lunar rock was ejected along the tangential direction of the shock wave. The number of fragments exceeding the lunar escape velocity could not be estimated. A considerable number of these fragments flew out of the lunar umbra shadow zone and were thus observed by astronomical institutions outside the Veil. This incident was covered up by the Foundation using conventional means. The test explosion also triggered a high-intensity moonquake, which even allowed the Foundation to observe the startled reaction of SCP‑179.

Since the moon has no atmosphere, there was no shock wave, the destruction caused by the fireball is limited. Within several minutes after detonation, it transformed from bright white to red and then broke, its geological effects were limited to the far side of the Moon. Within the following year, nearly the entire Moon was covered by radioactive material that fell back to the lunar surface without reaching escape velocity. Areas with relatively high radioactivity did not drop to twice the background level until 1955.

Summary
[[/hcell]]
[[/row]]

[[row]]
[[cell style="background-color:#000" class="log"]]

The test denotation was successfully completed.

The structure of AN-███.1 is considered workable, the Foundation's Nuclear Physics Design Department is working on the design of its production line. Due to the sensitivity of this behaviour, including the consideration of the possibility of causing a global atomic crisis and nuclear frightening, the Foundation will apply a series of protocols to ensure AN-███.1 would be only used by UDEM.

It was unanimously agreed that this test explosion served as a model of successful cooperation between the Foundation and the Coalition, which to some extent eased tensions of the Veil. The Foundation classified the true purpose of AN-███.1 as top secret throughout the process, ensuring that this unstable element was strictly secured, contained, and protected.

The DOEOW based on the above facts and made a comprehensive assessment of the progress of Project 634, reaching the following conclusion: Project 634 is proceeding smoothly. The first fully functional UDEM device will be installed at Area-CN-27 and Area-634 within one year. For administrative convenience, the UDEM devices at different facilities will be categorized as separate instances of a single Thaumiel-class anomaly.

The temporary number of the anomaly is: **SCP-CN-3969**.

**Abstract:** As the Project 634 is designated as SCP-CN-3969, the research and develop phase gradually ended. From 1950 to 1952, Project UDEM occupied one-third of the Foundation's budget, most of which was used in preliminary planning. After the production line is decided, the cost of AN-███.1 and "██"████ gradually decreased. DOEOW stated that the first fully-equipped UDEM devices will be installed at the critical sites of the Foundation.

Er. I think something is off. Look at this.

But the connections between this theory and Project 634 is still confusing, perhaps Fedorov thinks that the physical process of the denotation of AN-███.1 needs this theory to explain? 

…anyway…I didn't wrote this……oops.

[[/div]]


[[div class="blockquote u-2"]]
##4c4cff|**@Tidal.AIC**##, who wrote this? 
[[/div]]

[[div class="blockquote u-1"]]
Isn't it by you?
[[/div]]

[[div class="blockquote u-2"]]
That wasn't me!
[[/div]]

[[div class="blockquote u-1"]]
Your behaviour has been under strict monitoring. I'm sure that these words were typed by you on the keyboard.
[[/div]]

[[div class="blockquote u-2"]]
What is stellar nucleosynthesis? What's the relationship between it and Project 634—— or, what's the principle of UDEM? 
[[/div]]

[[div class="blockquote u-1"]]
Addressing a lot of questions in a short time will put me in a difficult situation. But I can try to answer it one by one:

1. Stellar nucleosynthesis is a theory addressed by Fred Hoyle in 1946. After further advances, it became the mainstream theory in astrophysics. This theory, especially the parts refined by B2FH, thinks high-mass stars through sequential multi-stage fusion reaction to generate iron element, and the elements whose atomic number is greater than iron is generated by the supernova whose core collapsed through the R/S process. 2.——
[[/div]]

[[div class="blockquote u-2"]]
Stop! Could you describe it in a more vivid way? 
[[/div]]

[[div class="blockquote u-1"]]
Ok, I will use a more vivid way to describe the stellar nucleosynthesis. We all know that the sun is a giant nuclear reaction furnace, it releases energy by continously fusion hydrogen into helium. When the hydrogen burns out, the hellium with great masses will collapse by itself, the great pressure makes helium start to fuse. The reaction of helium releases less energy, and burns faster—at this point the life of the sun ended, its temperature will drop, the outer layer expands and the inner layer shrinks, eventually it will become a white dwarf that nobody knows. It has moved forward to the eighth element oxygen, then falls into silence.

But stars with greater masses have the capability to walk down this road. The carbon got squeezed together, crossed the coulomb barrier and became neon, neon became magnesium, magnesium became silicon, the heavier the element, the shorter the time it holds. Helium can burn for millions of years, but from silicon to iron would only take 14 days. Now we have moved forward to the twenty-sixth element on the periodic table.

The fusion reaction would cause a lot of free neutrons, the iron element would absorb these fast or slow neutrons and form heavier elements, this is the R/S process. For those stars with an enormous mass, near the end of their lives, the core structure collapses fast and shatters, eventually become a beautiful firework—a supernova. Under these extreme conditions, the R/S process makes us move forward to the heaviest element in nature: the ninety-second, uranium. Elements after that won't be left in any cases, they are too unstable, they would completely decay before the planet forms.
[[/div]]

[[div class="blockquote u-2"]]
In this term, the nuclear explosion of AN-███.1 is an emulation of a dying star in fact.
[[/div]]

[[div class="blockquote u-1"]]
I think so, the heavy nuclear fusion environment of AN-███.1 is similiar with stellar nucleosynthesis. The denotation parts of AN-███.1 including some hydrogen bombs at one-hundred-million level, perhaps this provided a similar extreme physical environment.
[[/div]]

[[div class="blockquote u-2"]]
But I still have no idea how UDEM works——Does it just rely on it? Generating heavier elements? What does this have to do with saving the world…
[[/div]]

[[div class="blockquote u-1"]]
According to the information we got, although we are still unable to explain this, your hypothesis is likely to be correct. I will try to fetch more information on this route. Now, the investigation continues.

Something is wrong.

Every so often, about once a day, there would appear some "Research Note" I have no memories. I can't delete them, only to hide them, leaving those unfamiliar is indeed makes me scared.

Tidal would ask me why I haven't chat with it for a long time. But I really had no impression, the investigation has already lasted for two weeks, now I'm getting more and more confused on the whole situation——

[[/div]]

[[div class="notation"]]

**To O5-1:**

The project went smoothly. I think I can finally report some good news: Two UDEM devices have been completed in Qinghai and Nevada at the same time. Of course there are a lot of follow-up works to be done, we are still discussing whether to install the defense system at the same level of SCP-2000—— replicate them using the technology we have now, to ensure their absolute safety.

I am doing some personal research these days—for this purpose I have to learn some new computer knowledge, you know that the technology used on AK9MKII is pretty advance. I have always hoped to make eschatology a more precise, strict subject, although I think, to some extent, UDEM shattered the wish. Of course, I don't mind sacrificing personal wishes for UDEM, since UDEM—— or SCP-CN-3969, it is the great work of eschatology.

Or the final project.

Secure, Contain, Protect.

——Directions. The key is direction, thoughts, whatever you love to call it, but I really think I've gone in the wrong direction. The principles of UDEM are sure to include stellar nucleosynthesis, but it also include other things. Relativity. Quantum mechanics. Dame, where did Tidal lead my thoughts? Why I forgot the Summit at Area-62, that's the key! The underlying principle of UDEM is sure to be designed at first, stellar nucleosynthesis is the implementation method, it's the means not the aim!

The real principle, it should be called, let me find…I should look at the original record, two weeks ago…

**To Dr. Prokopiy Fedorov:**

Discussing others behind them is a shameful thing, however——I had no choice but to write you this letter. If you take this letter to William, I won't have any complaint.

Let me go directly to the subject. William Fritz recently behaved very abnormally. Unlike what he was when leading 634…I'm sure that something terrible happened to him, ever since he stepped down from the front line. I heard that he went to the Department of Physics very frequently these days, half of the uptime of AK9 has been used by him to run some eschatology models. I'm not suspecting he's doing something bad, and I can't suspect him, but…I was really worried about the psychological situation of William.

If possible, talk with him. I remember you two got along quite well, especially during meetings.

I found it. "Decoherent histories guiding system".

The subject of Department of Physics…"Mortise-Tenon"."orientedly decide past histories almost at will".

The answer was there at the beginning. I don't believe //it// won't notice.

But, now we have both the answer and the question, I have no idea about the process. Where to find the last jigsaw?

**To Dr. Christopher Zartion:**

Don't worry about William. He was like this when working at Yellowstone.

But——let me explain in this way, I'm really worried about this, not William, but how he became this. William is among the people who discovered Yellowstone's flaws first. We can realize that from the report to Overseers and that letter, he is sensitive to the potential risks of this kind of important project. Yes, it means he is likely——very likely——to think SCP-CN-3969 has some potential flaws.

Also, I need to admit that those physicists who have spoken to him all look extremely grim. I haven't asked what they have talked about, possibly related to that eschatology model.

The following document is excerpted from the High-Confidence advanced academic discussion record held in Area-██ by the Department of Physics of the Foundation on February, 1949. Due to the readability, Tidal.AIC has organized the original file, and simplified parts of the physics derivation process. Despite this, we still assume that the reader has a basic knowledge of mathematics and microscopic physics. The summary part of the file is relatively concise and may be used for reference.

AIC's capability to summarize academic content is relatively low, especially when the original document involves a large number of formulas, errors may occur, but in most cases it doesn't affect the credibility of the summary part.

Several months ago, the high-energy physics research facilities in Area-RU-21 took an important step in synthesizing superheavy elements. Briefly, the traditional superheavy element synthetic route is to use lighter elements to hit the pure target of another element in a great number, looking for the combination to synthesize superheavy elements under different physical conditions. This route will become harder as the atomic numbers rise. The extremely short half-life makes the detection of products a challenge.

Area-RU-21 addressed that, it is possible to create stable superheavy elements using a process similiar to stellar nucleosynthesis, the elements synthesized by this method are likely to bypass elements No.100~125, and directly synthesize the more stable Unbihexium (Ubh), the 126th element. Under high temperature and pressure situations, the R/S process using iron as seed nucleus will intesify, at a certain critical state, several iron atom may stimultaneously happen the S-process at extremely close distance, therefore generating stable superheavy atom.

The newly constructed Large Hadron Collider enabled Area-RU-21 to successfully create the extreme temperature environment required to verify this hypothesis. The iron‑californium target collision experiment produced an extreme temperature of 2.7 trillion Kelvin, and at least 1733 atoms of Element 126 were successfully detected. The most abundant isotope of this element has a half-life of 13,000 years and has been named Aeoniosium by the Foundation[[footnote]] originating from Greek "Αἰών"[[/footnote]]


-----

The successful synthesis of Aeoniosium made the DoP realize the possibility of creating superheavy elements through a stellar-nucleosynthesis-like process. Previously, many theories considered that the end of the periodic table is determined by the stability of the atomic nucleus, some pessimistic theories even think it is impossible to reach elements after 126, the more optimistic ones think the element 160 is the extreme of the periodic table. After this experiment, the DoP reached the conclusion that the extreme for the conventional hit method is element 119, only by a stellar-nucleosynthesis-like process can synthesize stable elements in period 8.[[footnote]]The Aufbau principle thinks the period 8 elements should be No.119~168, but as the atomic number builds up, the electron distribution of period 8 elements would be very strange, such as preferentially filling the 8p1/2 subshell. Theoretically the last element of period 8 should be element 172.[[/footnote]]

But at this time, the barrier that prevents the synthesis of new elements is not the half-life, but the contradiction between relativity and quantum mechanics. To overcome the barrier of element 172 in period 8, we must face the following paradox.

According to the Bohr model, the expression for the radius of the 1s subshell is

[[=]]
[[$ r = \sqrt{1/Z^2 - 1/c^2} $]]
[[/=]]

In which[[$ Z $]]is the atomic number, [[$ c $]] is the speed of light.

Under atomic units, [[$ c ≈ 137 $]] (Which is the reciprocal of the fine-structure constant). So, for the elements after element 137(Usually called by Richard Feynman's name, Feynmanium), the Bohr model predicts that the velocity of their electrons on the 1s subshell would be faster than light, and their orbital radius is less than zero. Which is visibly absurd, but even if we consider the effect of the relativity and the radius of the atomic nucleus, the critical value can only be pushed to 173. After element 173, the velocity of electrons cannot drop below the speed of light, or the atom would collapse immediately. But the electron is a matter that carries information, the relativity won't allow that.

-----

The stellar-nucleosynthesis-like process offered the possibility to directly verify this hypothesis: Approaching Element 173 and observing the physical properties of superheavy elements near it. New experiments were carried out immediately, after testing thousands of initial parameters, element 172 was successfully synthesized, but the observed data had abnormal values that were confusing. After highly complex reasoning, the researchers participated in reached the same conclusion: The synthetic process had produced traceable amount of element 173, and its superluminal electron partly "dragged", or "reversed" the spacetime around it.

The following inference remains highly advanced even by current standards: If the experiment is scaled up further and a large quantity of element 173 is produced, the strength and scope of this retroactive effect will grow exponentially. Eventually shows as macro, EPR-paradox like retrodeterminism. Element 173 actually caused a spacetime paradox, the history branch leads to the massive production of Element 173 would lose its coherence, so any observable history won't produce any Element 173.

So, a decoherent histories guiding system can be built up based on the effect, ensuring the stable trigger of the production of Element 173 at critical nodes, we can ensure history won't get to this node. So, by triggering decoherence on unwanted history branch, the system can guide the history to a intentioned direction.

This is called the Ultimate Anthropic Principle.

Although it has many technical issues, like the activation of decoherence needs a super accelerator approximating the circumference of the Earth, theoretically the decoherent histories guiding system is still has a high possibility to be implemented. The Department of Physics keenly recognized the dangers of this theory. So, the discussion documents, experimental data, and reports about the subject "Mortise-Tenon" were all sealed semi-permanently.

Summary
[[/hcell]]
[[/row]]

[[row]]
[[cell style="background-color:#000" class="log"]]

Stellar nucleosynthesis like process can create elements with a high atomic number, in this case Element 173. This element's inner layer electron has a velocity higher than the speed of light, so a decoherent effect was created. When a great amount of Element 173 exists at the same time, it is possible to decoherent the whole universe, in a macro view the universe returns to the time that without the production of Element 173, the history tree also returns to a branch that won't produce Element 173.

By controlling the production of Element 173, the decoherent histories guiding system can arbitrarily control the course of history. Due to this dangerous nature, this subject is sealed.

Recently I'm very anxious about the calculation result of AK9MKII.

…Anyway, the problem is way worse than I think. I have the responsibility to told the concerns to you, because this actually proved that SCP-CN-3969 has a grave problem—not on principle or engineering, it's something more complex.I have no confidence in dealing with it properly.

Now it is sure that Area-CN-27 can't be found on maps, because that was an underground site. Right below me.

Technically, the whole UDEM is divided into two sub-projects: AN-███.1 and——the more mysterious activation device, the former one just produced only a dozen or so units and then stopped, and the latter one was equipped in almost every site. I think so, because the Overseer Council said that…"Every site should equip a personnel that can remember this device".

It is certain that the three complete UDEM is installed in Site-01, Area-634, and…Area-CN-27.

Dr.Fritz? I think we need to talk.

[[span class="name"]]**O5-1**[[/span]]
What are you doing recently? This makes people anxious, really.

[[span class="name"]]**Dr. William Fritz**[[/span]]
Even make an O5 feel anxious?

[[span class="name"]]**Dr. William Fritz**[[/span]]
//(Sigh)// One, I think I'd better directly tell you what happened.

> William Fritz turned and walked into the office. O5-1 was following him. For a period of time, they haven't said a word. The paper that almost occupied the whole wall was actually pieced together from many A4 papers. On the left and right sides, there were many formulas, but the figure in the middle made people confused.

> That's hundreds, perhaps thousands of lines with arrows, spreading outward in a radial pattern, each line is marked with a lot of complex parameters. They all gather on a single plane.

This is the second generation of eschatology model based on number theory.

Based on the AK9MKII type computing engine, the great computing power can enable us to emulate the parameters of E.O.W factors. Unfortunately, the result of the model is…very strange.(Pointing behind him) Those lines were the result of drawing those factors in some corresponding principles, as you can see…they seem all gathered on a "plane".

[[span class="name"]]**O5-1**[[/span]]
The so-called plane should also be some more abstract thing, on mathematical meanings, right?

[[span class="name"]]**Dr. William Fritz**[[/span]]
This is the problem I'm working on these days. To be honest, I have a bad feeling in the beginning, I don't even dare to ask others to help.

[[span class="name"]]**O5-1**[[/span]]
Your feelings turned into reality? 

> Long silence, William Fritz gazed at the complex equations and coordinates.

[[span class="name"]]**Dr. William Fritz**[[/span]]
Yeah, it is real.

The plane does not exist in previous models, so it means no one knows its meaning—this is most likely to be some inherent commonality of the E.O.W factors, but what is it specifically? The collapse of cultural awareness? The decline of universal values? The evil inside humanity? Or some trap set by some supreme divine beings? What allows E.O.W factors to exist? 

In other words, One, What's the most accurate definition of doomsday—— K-Class Scenarios in your mind? 

[[span class="name"]]**O5-1**[[/span]]
…Er, let me think. The end of humanity, or more specifically, Unexpected incidents that cause the total collapse of the organized order of society?

[[span class="name"]]**Dr. William Fritz**[[/span]]
Then you would find out that the concept of "Doomsday" is The concept is something constructed from a human perspective. From a macro view, the "doomsday" we thought in universthe e is just normal celestial body collision, supernova burst, or changes of pattern in anomaly theology.

[[span class="name"]]**O5-1**[[/span]]
Does that mean you think doomsday is a concept contradics with civilization? 

[[span class="name"]]**Dr. William Fritz**[[/span]]
Everyone thinks so, this is the theoretical basis of the first generation of mathematical model on eschatology

> O5-1 seemed wanted to say something more, but he realized the deep meaning behind the words of William Fritz. The second generation. What does it change? 

[[span class="name"]]**Dr. William Fritz**[[/span]]
The principle of SCP-CN-3969 is easy, decoherence. The history is pulled back to the crossroad where we made our last choice, then change a road and continue, like nothing ever happened.

And the criteria to judge whether to activate SCP-CN-3969 and roll back history, is whether the doomsday will happen, in other words, like what you say: whether the organized order of society would collapse.

[[span class="name"]]**O5-1**[[/span]]
Is there any problem? Wasn't that the designed purpose of UDEM? 

[[span class="name"]]**Dr. William Fritz**[[/span]]
Yes, SCP-CN-3969 achieved this purpose perfectly.

> Silence.

[[span class="name"]]**Dr. William Fritz**[[/span]]
All E.O.W factors are on one plane, as long as we leave that plane, as long as the parameters that describe our civilization are perpendicular to this plane, those E.O.W factors won't have any projection on our vector, doomsday would never come, the order will exist, but the problem is——

The parameters describing E.O.W factors, at the same time, are the parameters that describe our civilization.

[[span class="name"]]**O5-1**[[/span]]
You mean that…

[[span class="name"]]**Dr. William Fritz**[[/span]]
The second generation of eschatology model works like this: Set up a vector with multiple parameters that describes the current state of civilization, then calculate to what extent the parameters have changed a civilization can be determined to encounter doomsday.

By iterating this process repeatedly, the result is the diagram in front of you: all the civilizations that encounter doomsday are roughly gathered at one plane, scattered in different directions, and the only civilization that owns UDEM, which is us, is perpendicular to the whole plane. For those important parameters that describe civilization, they are all zero.

Our civilization is a chaotic system, any tiny disturbance will greatly impact the prediction of the future. The Ultimate Deus Ex Machina continuously adjusts our history, making that vector leave that plane slowly, and the civilization itself will become a dead body. This is not a new K-Class Scenario, the world still exists, but the things happened on us can't be described by language completely, in a not so appropriate analogy——

A bad story without miracles, and being locked in fate, that goes on infinitely.

[[span class="name"]]**O5-1**[[/span]]
That's impossible…You mean what we have done is all meaningless? 

[[span class="name"]]**Dr. William Fritz**[[/span]]
(Sigh) I must admit, One, as the founder and leader of the Department of E.O.W, the purpose of eschatology shouldn't be to avoid doomsday, but to deal with doomsday actively. The civilization loses doomsday also loses its sense of urgency, loses the ability to unite as one in the face of crisis, and thus loses its qualification as a civilization. The eternal order has no difference with death.

One, I hope…to end Project UDEM permanently. As soon as possible.

> No one answered.

> The lights in the office went out. Darkness covered everything.

> O5-1 walked out thof e office. The lights of the corridor were still broken, and after a dragging sound, the door of the office closed by itself.

…The whole Area-CN-27 is underground. I don't know why I came here…I can't even remember the purpose. I only know that something is hiding here. Wait.

[[span class="name"]]**Gernica**[[/span]]
Yes, every site should have an activate device, the size…I don't know how big it should be, but it should fit in a briefcase of suitcase. The looking…has a great possibility that it is sealed all the time, and I can't find the blueprint.

Even I find the container, I can't get in. There are no card readers. At the time of the construction, there wasn't a card identification technology.

> The steps continue.

[[span class="name"]]**Gernica**[[/span]]
But who cares, the thing is just getting weird.

I feel really weird now. I'm sure that before I came I already overdosed on cognitive hazards protection drugs, and Mnestics, but—— whatever. I believe my intuition.

> She pressed the same button five times, then pulled a lever. Everything seems to be done by muscle memory, just like she had already been there before. The door swiped open silently. There's almost nothing in the container, just a table, and a briefcase.

Which site did I belong to before? 

As long as I know, three months ago I was working in some places other than 27, and the memories before that have another great blank, why haven't I discovered earlier…

So why I came here and investigate this CN-3969, what's the reason? I'm working on some chores at the documentation department, but what was my job on the last site?

By the way, why were the documents of CN-3969 covered by antimemes…

…antimeme[Unable to recognize]…?

I made a mistake.

I know that O5-1 can't just stop the UDEM. It equals to admit his failures.

Building UDEM is a mistake, so I chose to make up for it actively. On the Christmas of 1952, at which time most personnel came home. Obviously they won't suspect what I was going to do, but reducing the number of witnesses is obviously better.

There were three UDEM at that time, the systems were completely independent of each other. I was in Nevada at that time. I could only consider breaking one of those—Obviously, now I realized it is completely pointless, that even can leads to the activation of the other two UDEM. But I was at the edge of collapse, so I couldn't think anything more.

I'm going to destroy the power supply of the nukes, and neutralize a part of SCP-CN-3969. I'm not from the Department of Nuclear Physics, I don't have its full design blueprints, but with sufficient clearance I can go to the core area of the device, and switch the system to debug mode, to ensure UDEM won't enable lethal defense measures. To be honest, I don't understand why I'm doing that at that time, or going to do.

Because when I got to the core area, someone was already there.

> When Gernica continuously walked to deeper places, she found that the lights stopped moving with her. When the last light went out, the darkness in Area-CN-27 500 meters underground covered everything. She anxiously looked for a long time to find the flashlight with her.

> The light of the flashlight illuminated a little area in front of Gernica, and she realized the tunnel into the container had ended. The space in front of her is wider, but there is only a wall standing in front of her coldly not far away. On the wall there was also a door to the control room here.

> Gernica gently pushed the door open, it seemed that no one had been there for decades, and the dust stirred by her movements drifted wildly in the light of the flashlight.

[[span class="name"]]**Gernica**[[/span]]
Is…anyone there? 

> The only answer she got is echoes fading away.

> Gernica found some control devices soon, thankfully the consoles has chinese labelled on them. She hesitated for a while, and pulled down the biggest red lever marked with [[span class="ruby"]]“备发电甲”[[span class="rt"]]BACKUP ELECTRICITY GENERATOR A[[/span]][[/span]].

> A short silence. Then, all of a sudden, heavy roars of mechanics filled the whole room. As the generator's roar gradually faded into a faint hum, all lights were opened automatically, and Gernica saw the whole place clearly.

> Different from what she had imagined, this was not the control room for some subsystem,this was the doomsday control room to start SCP-CN-3969. Where she was was just a small corner of the control room. In the distance, behind the more complex devices, there's a glass curtain wall, through which you can see the whole look of SCP-CN-3969.

> In other words, the whole look of SCP-579.

> Four AN-579.1 superheavy nuclear fusion hydrogen bombs were placed on the wall, they have no outer shells. For the outsiders they can only see a bunch of complex pipelines, but Gernica can feel a speechless sense of oppression.

> This is the nuclear bomb unprecedented in human history, and likely never to be seen again. If anyone presses its start switch, the inner plutonium fission bomb will detonate first, before the nuclear fireball blooms for even one-thousandth of a second, the outer layer of tritium fuel will begin fusion, and an even greater fireball will break free from the device. Several nuclear fireballs will together surge toward the third layer of liquid iron fusion fuel, forcibly igniting the nuclear reaction—one that should only occur inside the nuclear furnaces of dying stars.

> Gernica could not help but tighten her grip on the briefcase handle, looking up above SCP-CN-3969, which had a more complex capture system consisting of more than a dozen mechanical arms. And right below it was an even more complex device—at its center there's a square hole.

> The location to place SCP-055, a high-energy physics device to create the heaviest element which has the shortest half-life in the history of this universe. The briefcase in her hand contained the quantum key needed to start this device. Once the key is captured by the mechanical arms, everything will go smoothly. First, the fuel tanks will be taken out, then the generator of the quantum key. The decoherence theory will take over the paradox created by the electrons on the f sub-shell of Element 173, and the fate that was meant to come.

> Gernica looked at the glass curtain, the control room is broader than her imagination, but the dark screens gave her a speechless sense of oppression. She decided to find a way to stop SCP-CN-3969 completely first.
p
> But the screens started to glow suddenly.

[[span class="name"]]**{{? ? ? }}**[[/span]]
//AREA-CN-27F main system power resumed…connected…proctol passed.//

> The power of the main system is resumed, following that came a stiff, mechanical voice. She looked to the screen in the sky, feeling shocked. At the time of the construction of this site, AIC or other similar things didn't exist.

> She saw all the screens displayed the same image. She can't be more familiar with that image. That's an avatar. The avatar she had been seeing for the past week.

[[span class="name"]]**Gernica**[[/span]]
Tidal?! How could you be here?!

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
I went over all the data we have at present. You haven't appeared in the site for the past four hours, and the site doesn't have your exit record. This made me believe that you are in some abandoned place in the site.

[[span class="name"]]**Gernica**[[/span]]
But the newest device here was developed seventy or eighty years ago——

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
The computer system here provided an interface similar to today's encryption method of the Foundation's network system. Although the interface can only transfer limited information, I can still operate some of the devices here.

[[span class="name"]]**Gernica**[[/span]]
Fuck. You just won't leave me alone.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
You are planning to neutralize SCP-CN-3969. I nrrd to warn you: This is a Thaumiel class item of the Foundation. According to the direct order of the Overseer Council, this item holds significant value to the Foundation.

[[span class="name"]]**Gernica**[[/span]]
SCP-CN-3969 must be destroyed or shut down permanently, Tidal, I can promise that leaving it here won't get us—everyone a good ending.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Your explanation can only make me fail to understand your behaviour.

[[span class="name"]]**Gernica**[[/span]]
Okay—— whatever you say. Anyway I will look for the manual and shut it down permanently, or other similar…

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
You think I can't stop you? 

[[span class="name"]]**Gernica**[[/span]]
Are you just gonna talk trash, or trip me with a robotic vacuum? You can't possibly be turning off the lights—that's boring as hell, Tidal. I brought a flashlight.

> Gernica shook the flashlight to one of the screens, and then walked to the filing cabinets, pretending nothing ever happened.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
I am going to warn again, assistance research Dr. Gernica. Without the permission of the Overseer Council, any destructive behaviour to a Thaumiel class anomaly is to betray the Foundation. The Foundation has reserved any possible measures for AIC.

[[span class="name"]]**Gernica**[[/span]]
Just shut up, please? 

> Like listened to her words, Tidal.AIC kept silent for a dozen seconds, but the screen still shows its avatar, which means Tidal.AIC was not leaving——

> Then, Gernica heard a strange voice. This voice seemed to come from the ceiling of the room. First came a strange sound of gears turning, then came some eerie buzzing, and the source of the sound was getting closer and closer to her. It grew louder and louder.

> The ceiling opened up a window. She realized there was indeed something wrong, bunkers which are absolutely safe, and highly confidential like this would obviously have some defense methods, especially around the core devices…

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
**Lethal measures unlocked.**

> As the words fell, several gun barrels poked out from the opening. From her perspective, she could also faintly see the reflection of ammunition belts inside the ceiling.

> Silence fell. Although she didn't cry out in fear, the camera on Gernica's chest shook violently. She even forgot she was holding a briefcase and let it drop to the ground.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Dr. Gernica, due to the speciality of this investigation, including possible cognitive hazard, your behaviour can still be tolerated.

In the meantime, to meet the confidential requirements, before the issue complete ends, I can't report this event. If you stop your threatening action immediately, events happening right now…

…No other people would know.

[[span class="name"]]**Gernica**[[/span]]
I…I'll agree, let's put that thing back, OK? 

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Refused. According to the Emergency Situation Protocol, you shall eliminate all threats you pose to SCP-CN-3969-Thaumiel. Only then will I be permitted to lift the threat against you.

[[span class="name"]]**Gernica**[[/span]]
(Sigh) Ouch…Okay, I'll leave the case there, and go back to the office and let you send the report. Is that sufficient?

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Acceptable.

> Gernica knelt down and tried to lift the briefcase, but she forgot that it was an old item that had been gathering dust for decades. After a fall, when she pulled the handle casually, the briefcase opened on its own, with the upper half of its interior facing her.

> From the perspective of the monitor, Gernica seemed frozen and stared at the content inside the case, and kept silent for a long time.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Gernica? 

> Gernica closed the briefcase. She directly looked at the screens controlled by Tidal.AIC for the first time, and the 5.9mm gun barrel under it.

[[span class="name"]]**Gernica**[[/span]]
…Tidal.AIC. I suddenly found something interesting…

You are just an AIC, an assistant AIC. The only task of you is to cooperate with me to investigate this anomaly.

What gives you the right to make decisions for me?

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
This is a serious, aggressive action——

> Before the words were even finished, Gernica threw the briefcase directly at the nearest screen, which just blocked the gun barrels below. This forced Tidal.AIC to hold its fire. After the briefcase hit the ground, Gernica had already slipped into the gap between the filing cabinets.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Oral warning failed. The object refuses to control its behaviour. Lethal measures enabled.

> Tidal.AIC redirected all machine guns to concentrate fire immediately. The sound of gunfire was deafening in the enclosed basement. However, due to the lack of visibility on Gernica's position, the first wave of bullets merely struck the metal cabinet doors at random.

[[span class="name"]]**Gernica**[[/span]]
Monitoring cameras won't exist before the 70s, you can just rely on the rough monitoring system——

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
You can't hide among those cabinets forever, Gernica. Stop all betrayal behaviours immediately.

> The second round of firing started, this time concentrated on the side exits of the rows of filing cabinets, gradually closing in toward the center. Even so, Tidal.AIC was soon forced to cease fire due to severe overheating in the defense systems.

> Taking advantage of the gaps in the firing, Gernica fled the cover formed by the filing cabinets. However, she soon realized that the open area of the control room was not safe, as Tidal.AIC was already attempting to re-aim. Just as Tidal.AIC prepared to open fire, Gernica found a standard-issue Foundation pistol on the table.

> Gernica aimed the nearest opening of the ceiling, switched off the safety, and pulled the trigger. At the same time, Tidal.AIC started to fire again. Gernica's bullets struck one of the firing gun barrels, followed by a series of dull noises. The barrel jammed and ceased movement, with a plume of black smoke drifting down from the opening.

> When Gernica was looking for cover, Tidal.AIC's covering fire finally hit Gernica

> A special 5.9mm bullet struck the upper part of Gernica's right arm. The impact sent her staggering several steps before she leaned against the wall. Strangely, according to the audio record, Gernica did not make a single sound throughout the entire incident.

> Gernica used the load-bearing wall as cover, opened the medical kit, wrapped an adhesive tourniquet once around the wound, then pulled it tight. The synthetic skin beneath the tourniquet bonded firmly to the injury.

> Tidal.AIC stopped the fire. The bullets in the defense system is actually low, and it wasn't being maintained for decades, the shooting before had already damaged most of the guns. Unfortunately, the guns that was still operable is right above Gernica.

> She looked up at the cold gun barrels.

[[span class="name"]]**Gernica**[[/span]]
…You just won't leave me alone.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
Isn't the situation clear now? Don't do your useless resistance, Dr. Gernica. What you have can't destroy these defense modules in one go.

[[span class="name"]]**Gernica**[[/span]]
//(Laugh)// Yeah, Tidal, how can I destroy those barrels just using this? But that doesn't matter. Why am I going to compare firepower to you? Look at the maps here, what is behind me? 

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
The maps in the database here is not precise to the extent that can tell me what's on the table. You can just tell me what you're going to do.

[[span class="name"]]**Gernica**[[/span]]
That's the network switch here, the only one.

> Tidal.AIC silenced for a long time. It was sure that it was conducting complex game simulations. Now, she and it have entered the classic mutually assured destruction dilemma.

[[span class="name"]]**{{Tidal.AIC}}**[[/span]]
After the switch was destroyed, the connection between me and here would be cut off immediately, and you can achieve your aim. But you still haven't taken action, which means you think destroying the switch is an adventurous behaviour: The only possibility is that you must turn around to aim the core of the switch. This means I'm still gaining the upper hand, because I can immediately launch a covering barrage the moment you turn around.

Based on the above facts, I have done 1,203 simulations under initial conditions with varying perturbations, your winning rate is zero. Even if you can open fire to the switch, the Foundation's standard pistol can't destroy the whole switch, which means you can't disconnect the connection and ensure you are not severely injured.

I sincerely suggested you stop all hazardous activities.

> Gernica pointed her gum to the screens controlled by Tidal.AIC.

[[span class="name"]]**Gernica**[[/span]]
After all you are just an AIC, even an AIC brainwashed by program. You don't have free will, even by a generalized definition. You won't aware that the play performed by you and me has been played from time to time, in different timelines and infinite universes.

I'll tell you what I'm going to do.

I'm going to start SCP-CN-3969, reverse the time to the point where the butterfly flaps its wings, and bring history back to its proper course. The UDEM shouldn't be built, but the Foundation would always be trying—If I failed to end this all today, there would be others. If the Foundation, or GOC, or anything tries to build UDEM again, there would always be someone to reset the history to its proper position, preventing us from horrible things that neither living nor dead.

**The existence of Ultimate Deus Ex Machina is a paradox itself.** Its birth is certain to lead to its doom, so in the past you can query, the Foundation would be the first one trying to build it. But it is likely, even inevitable, this trial has been conducted for hundreds of times, every generation of organization that maintains the Veil would try to control this power.

And they would fail.

And do you know the funniest thing? In this cycle, it is you who is trying to fight for the fate, Tidal, an assistance AIC. You even have no idea of what you're doing, you just follow the orders the Foundation gave you and execute them rigidly…trying to achieve the unachievable…This is indeed…

{{…disgusting.}}

> Gunfire erupted from behind Gernica. She had been hiding a large-caliber pistol behind her back in her right hand, probably snatched from the table in the chaos. Then, the switch was blown with a big hole immediately, with white smoke blowing out. Tidal.AIC sent the fire order, but it failed to reach the defense modules. The underground area is completely isolated.

> Then, she unplugged the safety pins of the two levers, and SCP-CN-3969 entered the standby mode. With a dull, loud sound, the glass curtain wall in front of her nearly shattered.  A several-meter-thick blast-proof wall rose from the outer rim of the main equipment platform, and it was not until the sound of the locking mechanism came from the ceiling several minutes later that everything returned to silence.

**Item #:** SCP-CN-3969

**Object Class:** Thaumiel

**Special Containment Procedures:** After parallel investigation it is considered that SCP-CN-3969 is a Thaumiel-class anomaly. MTF-CN-███, MTF-███/███ have already been ordered to enter the location of SCP-CN-3969-Thaumiel instance (aka the UDEM device, refer to the document below), protecting it from destruction and activation.

**Description:** SCP-CN-3969 is a megaproject directed by the Department of E.O.W in the fifties of the last century, the code name is 634. The final product of this project is "Ultimate Deus Ex Machina", which is SCP-CN-3969-Thaumiel. Its essence is a semi-automatic decoherence histories guiding system. The detailed anomalous nature of the item is described in the investigation report 3969-A.

Limited by its anomalous nature, in order to investigate the history of SCP-CN-3969, more than fifty foundation personnel were assigned to conduct a parallel investigation, and demanded the assistance artificially intelligent conscript Tidal.AIC to collect information simultaneously. However, Tidal.AIC was under malicious hijacking attacks during the investigation, this uncontrollable factor eventually led to the happening of Incident 3969-⨀. Notably, the ███ Department may be responsible for this incident. [Insufficient Clearance] is being ordered to investigate this department.

The whereabouts of former Foundation personnel Dr. William Fritz are under investigation.
