Dictum Mortuum

The dictum mortuum, or "code of the dead" is a set of laws laid down by Charon and enforced by the Hierarchy governing appropriate wraithly behavior vis-a-vis the quick. The dictum mortuum explicitly forbids Stygian wraiths from interacting with the living: communicating, using Arcanoi that allow them to breach the Shroud, or otherwise impacting the living. The dictum mortuum made certain guilds de facto illegal.
