Hriston
Dungeon Master of Middle-earth (He/him)
A classic choice for D&D that would more or less fit this description would be to play a larva, lemure, or manes from the lower planes who has been selected to form a ghast, imp, quasit, shadow, spectre, or wraith. By the time this happens, their mind and any memory of their past life would have been obliterated by the torment they have suffered.no more like something that is always undead, maybe it once live in it distant past but it became a species of unlife.
