This guide has been rewritten as part of the 2014 background guide overhaul. The original version of this page can be found in archive form here.
Changes From Original Version
- The primary definitions of Safe, Euclid, and Keter have been reoriented primarily around difficulty of containment, as is colloquially used on the site.
- The list modules have been removed to make room and cut down on the number of tabs.
- The common rule of thumb that states that sapient entities should be Euclid by default has been codified.
- Primary and Secondary classifications have been separated for clarity.
- Thaumiel as an object class has been codified.
- Decommissioned has been removed from the in-universe guide and moved to the Writing Guide.
This guide was written with the help and input of all senior staff members.
