Lich

Liches are a species consisting of quasi-dead formerly-mortal voidist magicians that live and breathe in deteriorating, corpse-like bodies sustained by pure magic. A lich ties him or herself to a bewitched object, which through void magic, is purposed to contain the lich's soul. So long as that object remains in tact, so shall the soul linger in the world. Whilst a lich does not need to remain in the same body and the destruction of the body is no true danger, any body the lich takes possession of will begin to deteriorate and any body with a soul therein will resist the lich's influence. Thus most liches remain walking corpses and learn to disregard the normalcy of mortality as they indulge themselves in the vice of power.
