Demonic Dark Lords of the Underworld

The Demonic Dark Lords of the Underworld are presumably demon co-rulers of the underworld, led by the Source of All Evil. In unity, they may be similar to the Triad or the Infernal Council.

The demon Katya served several Demonic Dark Lords before she went rogue, wanting to make a name for herself having seen lesser evils awarded for their deeds when she was not.
