Banehold

The Barrens of Doom and Despair is an evil-aligned plane of existence. It is one of a number of Outer Planes, one of inhospitable locales, including vast deserts of black sand and huge plains of dark granite. There is no water to be found anywhere on the plane, and no sunlight fills the blood-red sky.

Five deities make their homes here, including Bane (his home was previously referred to as Acheron), Beshaba, Hoar, Loviatar, and Talona.

Structure
The Barrens of Doom and Despair consist of a single infinite plane, there are no constituent layers. It links via the Astral Plane to the planes of the Prime Material (such as Toril) and a number of portals directly connect it with Hammergrim and the Blood Rift. Besheba's realm, the Blood Tor, links directly to the Abyss.
