The Gaping Maw

The Gaping Maw was the 88th level of the Abyss and the home of Demogorgon, Prince of Demons.
Reflecting the dual personality of its master, the Gaping Maw was a vast continent covered in a jungle and surrounded an equally vast ocean with brine flats. Rising from the sea were twin towers, topped with enormous fanged skulls that marked the fortress Abysm, a labyrinth of dark and cold underwater caves. Few could enter without succumbing to madness.
Inhabitants and Notable Locations:
The jungle portion of the realm, known as the Screaming Jungle, was inhabited by troglodytes, lizardfolk, hezrou, yuan-ti, dinosaurs, dire apes, and barlguras. It held a two-way portal connecting to the Guttering Grove. Together with Slugbed and Shedaklah, this was one of the layers whose jungles were inhabited by threeb, a type of leech that was the main ingredient of the Quelaerel sauce.
The ocean portion was inhabited by aboleths, ixitxachitl, and krakens. Demogorgon's lair was in the palace of Abysm: two serpentine towers topped with skull-shaped minarets whose bulk extended deep underwater into dark caverns. The deepest of these caverns and the deepest trenches of the ocean were connected with the Shadowsea.
