ORCUS, DEMON PRINCE OF THE UNDEAD, is one of the most powerful demons in the Abyss—powerful enough to threaten gods. He commands legions of followers, living and dead, and cults dedicated to him are terrifyingly widespread in the natural world.
Orcus finds amusement in the suffering and anguish of the living and satisfaction only when he drinks their blood. Most living things enrage him by their mere presence, and Orcus
permits only undead to be near him; even his demon servitors are undead. He has destroyed hundreds of mighty heroes and laid waste to countless kingdoms.
Orcus is a foul and corpulent humanoid creature who has powerful goat legs and a desiccated head similar to that of a ram. His great wings stir up a reeking cloud of diseased air. He seems somewhere between life and undeath—his soreridden body suggests diseased life, but his head and glowing red eyes suggest undeath. His thick, spiny tail is in constant motion.
Dead creatures respond to the presence of Orcus, even without his command. Skeletal arms claw up from the ground where he walks and grab at the feet of his foes. Spirits fill the air with a ghostly chorus of piteous moans, tugging at his foes and hindering their movement.
