Ghouls are ravenous spirits of the dead, bound by magic in lifeless corpses. Ghouls are tormented beings, filled with hatred for the living. Powerful Necromancers can control them, but otherwise they are wild and destructive. Transformation into a ghoul is used as the ultimate punishment in Heresh, and is a means of permanently removing a soul from the cycle of death and transformation. Ghouls feed on corpses and often carry diseases in their blood and saliva.
