Layers of the Abyss
The Gaping Maw
The Gaping Maw is said to be the 88th level of the Abyss, though it fluctuates up and down the various planes of chaos. Notably, The Gaping Maw 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".
Thanatos
Nicknamed the "Belly of Death," Thanatos is the 333th layer of the Abyss. Its corrupted landscape boasts endless decay, and its residents yearn for the opportunity to drain the life force of any non-dead entity that wandered within. Any being that does perish upon Thanatos is raised as some form of undead or lesser demon within an hour's time. It is most notably the realm of the Demon Lord Orcus.
