Glaugust: On the Raised Dead
Raising the dead is simple: the idea it isn't persists due to the ongoing spat between formerly sister cults.
The ritual is as follows: gather the blood of a hundred men, boil it down to a gravy, serve it to the unwitting, and use their nightsoil to spread over the graves of the soon to be living dead. It is cut and dry. The point of distinction comes from how the undead are greeted once risen.
Dabirag and his followers insist that the a name should be chosen from the blood of the hundred-slain as their essence is what moves the flesh.
Unbir and her dancers say that only the name of the risen corpse can be used to refer to the animated death. She's insited for centuries that the hundred-slain paste is just the pitch needed to respark the original fire of life.
