Orcus

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. Orcus rewards those who spread death in his name by granting them a small portion of his power. The least of these become ghouls and zombies who serve in his legions, while his favored servants are the cultists and necromancers who murder the living and then manipulate the dead, emulating their dread master.
Orcus is a bestial creature of corruption with a diseased, decaying look. He has the lower torso of a goat, and a humanoid upper body with a corpulent belly swollen with rot. Great bat wings sprout from his shoulders, and his head is like the skull of a goat, the flesh nearly rotted from it. In one hand, he wields the legendary Wand of Orcus.

Realm

Orcus makes his lair in the fortress city of Naratyr, which is on Thanatos, the layer of The Abyss that he rules. Surrounded by a moat fed by the River Styx, Naratyr is an eerily quiet and cold city, its streets often empty for hours at a time. The central castle of bone has interior walls of flesh and carpets made of woven hair. The city contains wandering undead, many of which are engaged in continuous battles with one another.
