Orcus

The bloated Demon Prince of the Undead seeks to end all life in the cosmos, replacing the living with immortal, undead creatures that answer only to him. In this grim future, the many suns of the Material Plane are extinguished, and all hope has faded away. All that remains is the eternally static realm of the living dead.

Orcus is the universes's staunchest advocate of stagnation. He sees the activity of live as noisy, crude, and maddening. It rakes at his senses like the claws of a rat scraching across a hard floor. In his view, the universe can know peace only when life's incessant hum is replaced with the peace and quiet of the world of the dead.
