Asmodeus, Lord of the Nine Hells

The greatest devil and ruler of all devilkind, Asmodeus was overlord of all the nine Hells. From his throne at the bottom of Baator the Lord of Lies reigned over his kingdom of unyielding tyranny, ceaseless warfare and political intrigue and enacted his diabolical plans to become not only the Supreme Master of the Nine Hells, but all existence. His sinister machinations could take centuries, if not millennia, to come to fruition, and his master plans extended across the entire multiverse.
Worshipers of Asmodeus do so for his oppression, power, indulgence, Evil, rage, and lies.
