Baalgar

Baalgars are demon Hell wardens.

Background
These demons are of the highest rank among the denizens of Hell. They offer service to no one--even the named demons. At first it was believed that this was in fact a unique demon, as it is held in reverence among the lower order, but a tablet found in the Temple of Corrax revealed that is a unique genus of demon only found deep within the bowels of Hell. Art of Doom, pg 57.
