City of Splendors & Horrors
At the bottom of the Elemental Chaos seethes the Abyss, a hideously corrupt reflection of the pure entropy that caps it. Black chasms connect the Abyss to the rest of the Chaos, and these places threaten both body and mind of any who dare to approach.
The Abyss teems with demons that answer to no authority except that wielded through might and fear. The strong bully the weaker. The most powerful demons lord over whole realms.
The features and realms within the Abyss are uncountable. They move and change with no explanation. Only a demon lord can maintain a region in accord with its warped standards, carving a meaningless empire out of the pervading ruin. Twisting through the insanity of the plane is the roiling River Styx, its waters poison and its course inconstant.
Alignment: Chaotic evil.
Primary Residents: Demon lords such as Baphomet, Dagon, Demogorgon, Graz’zt, Kostchtchie, Orcus, and Yeenoghu.
