Udralak the Extinguisher

A extremely evil human necromancer wizard who had a lair in the Desert of Pliny 3000 years ago, until an unknown force used magic to bury his lair under a colossal sand dune, sealing him in there and putting him in suspended animation, until the magic wore off and his lair was explored, and himself captured by, The Legion of Llandos.

They were forced to slay him, but he later turned up alive as a member of The Black Chorus, and was the only escapee from their battle with the Legion. His whereabouts and activities are unknown.
