Asmodeus

Asmodeus (az-MO-dee-us), an archdevil before the Sundering, Supreme of the Nine Hells (or Baator), was the god of sin. An ever ambitious and careful creature, Asmodeus retained his position all through the Reckoning of Hell, unlike many of the other archdevils. Asmodeus was lord of Nessus, the Ninth Layer of Hell, though he was generally recognized as lord of all of his divine dominion of Baator, which lay within the Astral Sea.

Asmodeus was the undisputed master of the Nine Hells, commanding fear and respect from all those who occupied his realm. Even the gods who dwelt in the Nine Hells gave Asmodeus his proper due. Though the archdevils might work to usurp him, few had the courage to act openly. Asmodeus’s machinations were long in the making, and they might take centuries, if not millennia, to see resolution. He worked on a grand scale, carefully constructing insidious and inexplicable intrigues, maneuvering the forces of wickedness like chess pieces on a board that encompasses all the planes.
