The Coriander Society uses several systems of classification to protect sensitive data from falling into the wrong hands.
But in some cases, there are no right hands.
Information classified as Delta Zero is hazardous to know. Merely being aware of the knowledge’s existence is considered dangerous, and actually learning and comprehending its contents is harmful or fatal. This may be through the attentions of a malevolent entity or a curse brought about by understanding the knowledge or information.
D-0 information is restricted by its very nature. Each file may have containment procedures, specialized conditions under which it can be comprehended safely, compartmentalization, or contingent circumstances that allow for its use—at terrible cost.
Many society members aren’t even aware that this level of classification exists. Discussion of this security level, content on this security level, or anything pertaining to either of the above, is to be avoided.
