The immortal Archdemons, claiming dominion over the inner most circles of Hell, rule as lieutenants of the Dark Lord. From the forsaken Deathlands to the formless Slough of Torment, all of Hell's minions submit to their behest. Most reviled of them is Erebus--Keeper of the Spire Cities of Dis, risen from the ruins of Babel. As Slavemaster of the Damned, he rules over the cursed souls of Hell, who are sentenced to labor without end. Though their power is near absolute, the Archdemons answer without question to the Nameless One, Infernal Master, and Lord of Hell, whose dominion is formless and ultimate.
In order of hierarchy.
