Editing SCP Foundation (section)

===Esoteric Classes===
The following Object Classes fall outside of the purview of standard classification.

*Thaumiel:  Anomalous material or entities that can be used by the Foundation to [[Ordo Xenos|contain or counteract the effects of other highly dangerous anomalies.]] Sometimes the best thing to do is fight fire with fire. Since its introduction, it's become an unofficial primary class, and is the fourth most-used containment class on the site.

*Apollyon: First used by SCP-2317 (iteration 6, Destroyer of Worlds which cannot be stopped and will destroy the world in the next 30 years) Apollyon is often derisively referred to as "Super-Keter."   This class is only used for anomalies that present an apocalyptic threat that the Foundation has no way of stopping, slowing down, or undoing.  For example: in one alternate timeline the sun became an Apollyon SCP when something caused the sun to start turning any living thing exposed to sunlight into blob monsters. This included trees, keters, ANYTHING. The author community mostly considers use of Apollyon to be in poor taste; this has been lampshaded in some Tales, like the Antimemetics Division tale [http://www.scp-wiki.net/the-wild-light Wild Light]: "Current thinking...is that Apollyon classification is a confession of defeat. It's bad for morale. It cultivates defeatist attitudes. [Keter is] the top of the hierarchy".

*Archon: One of the more popular esoteric classes, Archon denotes items that would do more damage contained than uncontained.
