A rogue celestial from the Lawful Good plane who became a devil while on the mortal plane. He was immortal and would never stay dead for long, always being reborn a short time after each of his deaths. For this reason, the enforcers from his old plane were unable to keep him for long.
He spread disease and plagues wherever he went, and his motivations were never learned. One of the plagues he spread reached the town where Cheryl grew up, and she harbored a desire for revenge against him for years. She and the rest of the party confronted him when he tried to flee the last city he would ever infect, and she got her revenge by sealing him in a gem from which he could not commit suicide and be reborn.
