The Foundation's primary directive is to order the anomalous by designating instances with four-digit numbers and methods of containment. One of the tools used to accomplish this is the Object Class, a process of parsing anomalies into groups based on the difficulty of containment. [[[Object Classes | Full dossiers are available for readers wishing to familiarize themselves.]]]

Despite this, some anomalies warrant entirely new object classes beyond the standard Safe, Euclid, and Keter, and sometimes even beyond Thaumiel, Neutralized, and Explained. These Esoteric Classes are exceedingly rare, and many are not viable for standard documentation due to their specialized natures. The following lists serve as a collection of these classes.

Given that additions to this guide are manual, it's very likely that some classes will slip through the cracks. If you have information on a class being improperly labeled in this guide, you can update it as appropriate!

++++* How to Edit
In order to change something, scroll down to the "Edit" button at the bottom of the page and open the edit window. Please list a description of changes made in the "Short description of changes:" window.

++++* Adding New Classes
Here's the code for an entry; place it alphabetically in the appropriate section.
[[=]]
[[code]]
||Class||Definition (if necessary)||[[[SCP]]]||
[[/code]]
[[/=]]
If a class fits into the following descriptors, it's eligible for being added here.

* **It isn't Safe, Euclid, Keter, Thaumiel, Apollyon, Archon, Pending, Explained, Neutralized or Decomissioned.**
 * Apollyon, Archon and Decomissioned were formerly eligible for this list, but have graduated and become standard.
* **It isn't a dual class of standard object classes.** A document labeled "Euclid/Keter" is not esoteric, but "Euclid/Ticonderoga" is, and the article should be added to "Ticonderoga" below.
* **It isn't the same as another class.** For example, "Esoteric" and "Other" are grouped together in the list below. This only extends to the similarity of definitions.
* **It isn't in a joke article.** Explained SCPs, tales, GOI formats, and everything else is fair game. Exceptions can be made for subclasses in joke articles that belong to an established subclass system.

//That's it, really.// There are some special cases for esoteric classes created by foreign branches, however. Namely:

* **It isn't the result of third-party manipulation, anomalous or otherwise.** These classes tend to be single-use and the purpose of including foreign classes is to increase cohesion between branches.
* **It's a subclass.** These should be added to the Subclasses section instead of the Foreign section.
* **Its article has been translated.** If this is the case, it is no longer considered a foreign class; treat it as a local one.

------

++++* Adding Or Changing A Definition

Definitions are only valid if they're sourced from an article, from an author who has used the class or can be reasonably drawn from "general consensus" in the absence of a definition.

Generally, self-explanatory classes like "Uncontained" should not be given definitions. If a class' meaning can be reasonably inferred from its name, then leave the definition slot blank.

------

++++* Precedents

* "N/A", "None", and "Unnecessary" are treated as separate classes due to slight variance in definitions.
* The "Location" subclass was added, despite having never been used, due to its necessity in completing the Type System.
* The multiple classes of [[[SCP-4205]]] were grouped together.
* "Scarf" and "Youklid" were added, despite being misspellings of standard classes.
* The poetry in the Object Class fields of [[[shaggydredlocks-proposal|]]] are not listed, because of their length and the proposal being listed under Apollyon already.
* [[[SCP-5708]]] was listed under the -prodest subclass despite not using it as a subclass, per the author's request.

++ Subclasses

Because several anomalies do not totally conform to standard object classes — while not warranting the creation of a new class themselves — several subclass systems have been created to further describe their properties and/or their containment.

[[div class="eso-list"]]
[[collapsible show="► Subclasses ◄" hide="▼ Subclasses ▼"]]
+++* Suffix System

The following subclasses are attached to standard classes (//e.g.// Safe-alterius) to denote attributes of the anomaly. Several of these classes lack established definitions; where this is the case, definitions have been inferred.

+++* Additional Systems

The following subclasses are used in a variety of formats and do not belong to a system that has been properly enunciated.

||~ Class ||~ Definition ||~ Appearances ||
||-Approaching/-Arriving/-Intruding/-Exited ||  ||[[[SCP-1463]]]||
||Dark||Item's properties are unknown due to them having recently developed.||[[[SCP-5761]]]||

||Extreme||  ||[http://scp-wiki-cn.wikidot.com/scp-cn-266 SCP-CN-266]||
||(Informal)|| Item's containment or status was achieved improperly. || [[[SCP-4736|]]] ||
||(Neutralized)|| Item has been neutralized but its effects persist. ||[[[SCP-3519]]]||
|| Paradox-Apollyon ||Item will inevitably destroy mankind and can be contained by the pre-emptive destruction of human life.||[[[swelling-of-the-worlds|]]][[footnote]] Original text: Ты - аномалия, опухоль миров [[/footnote]]||
|| Paradox-Thaumiel ||Item has been created to totally destroy human life via a localized ZK-Class Scenario.||[[[swelling-of-the-worlds|]]]||

||(Unknown)||Item's location and/or properties remain undetermined.||[[[SCP-3005]]]||

+++* Anomaly Classification System Secondary Classes

The [[[anomaly-classification-system-guide|ACS]]] adds two more class types to the usual Containment Class; Risk Class and Disruption Class. While both of these have their own five standard classes, esoteric forms of each do exist;

||||||||~ Disruption Classes||
||Chaya||Item is deeply seeded within human culture. Although widespread, human consensus considers it non anomalous, and disinformation is not necessary.||[[[SCP-6153]]]||
||Infrared||The amount of disruption that this item can produce/is producing cannot be discerned.||[[[SCP-6445|SCP-⌘]]], [[[SCP-6183]]] ||
||Erloschen||May cause great shifts in reality, however due to altering reality these effects are considered normal.||[[[SCP-6651]]] ||
||Micantia||Disruption level varies wildly over a short period of time||[[[SCP-6748]]] ||
||Cyber-Amida||Disruption level is equivalent to Amida, except that its effects are limited to only the Cybersphere.[[footnote]]The sum of all digitally/electronically-stored data.[[/footnote]]||[[[SCP-6488]]]||
||Metamida||Disruption level of an Anomaly extends to the Multiverse||[[[SCP-7243]]]||
||N/A||Disruption class is inapplicable due to the veil being broken.||[[[SCP-6115]]]||
||N/A|| ||[[[SCP-6594]]] ||
||Null ||Item is intentionally exposed to the populace, making a disruption class inapplicable. ||[[[SCP-4352]]] ||
||Ohr||An anomaly with the ability to redefine normalcy / the Veil, but in a manner which renders such changes undetectable.||[[[https://scp-wiki.wikidot.com/jack-ike-s-proposal-iv|Null Sum Proposal]]] || 
||Gevurah||Same as the containment class of the same name.||[[[SCP-6993]]] ||
||Undetermined, TBD|| ||[[[SCP-3644]]], [[[SCP-6079]]]||
||INFLUENCE||An abstracted form of SCP-INTEGER's original Disruption Class.||[[[scp-5242|SCP-INTEGER]]] ||
||None|| ||[[[SCP-5214]]], [[[SCP-5729]]], [[[SCP-6751]]]||
||||||||~ Risk Classes||
||Cryptic|| The amount of danger that this item can produce/is producing cannot be discerned.||[[[SCP-6183]]]||
||Mercurial||The nature of the danger that this item presents is constantly shifting.||[[[SCP-6445|SCP-⌘]]], [[[SCP-7805]]]||
||N/A|| ||[[[SCP-6594]]]||
||Tangent||The effects of the anomaly are theoretically extreme, but would not be recognised as such. ||[[[https://scp-wiki.wikidot.com/jack-ike-s-proposal-iv|Null Sum Proposal]]] ||
||VOLATILITY||An abstracted form of SCP-INTEGER's original Risk Class.||[[[scp-5242|SCP-INTEGER]]] ||
||None|| ||[[[SCP-5214]]], [[[SCP-5729]]], [[[SCP-6751]]]||
