Acererak began as the half-fiend son of an Orcus-worshipping balor, became apprentice to Vecna, and spent thousands of years engineering his own apotheosis.

His Tomb of Horrors has killed more adventurers than any other dungeon in D&D history.

His Soulmonger nearly fed a stillborn god enough stolen souls to reshape the rules governing death across an entire world.
