Abysm

Demogorgon's Home, the Screaming Jungle, also called the Gaping Maw

Abysm is said to be the 90th level of the Abyss, though it fluctuates up and down the various planes of chaos. Notably, Abysm is the home plane of Demogorgon, one of the Demon Lords of the Abyss. He resides in a massive dual-skull kingdom known as "The Screaming Jungle".
