Demogorgon, the self-proclaimed Prince of Demons. These cultists garb themselves in costumes that resemble the two-headed beast they worship. Their two-faced, monstrous masks and tentacled sleeves strike fear into those they aim to subjugate. Like the demon lord they worship, cultists of Demogorgon revel in chaos, domination, and destruction.. At some point however, the tanar'ri demons rose up against their obyrith overlords and defeated them, slaughtering most obyriths making them very rare now, though some did survive. The Abyss is now ruled over by the tanar'ri and their demon lords with the current Prince of Demons (the greatest of the demon lords) being Demogorgon.
His (self-proclaimed) title "Prince of Demons" puts him in direct competition with other, ultra-powerful demon lords, especially Orcus, the Demon Prince of Undeath. The two demons are locked in a more-or-less constant blood feud and devote a great deal of their energies and followers to fighting ceaseless, brutal proxy wars.. Orcus is the Demon Prince of Undeath, known as the Blood Lord. He takes some pleasure in the sufferings of the living, but far prefers the company and service of the undead. His desire is to see all life quenched and the multiverse transformed into a vast necropolis populated solely by undead creatures under his command.
