The Lower Planes

The Gaping Maw is a hellish layer of the Abyss, ruled by Demogorgon, where salt flats intermingled with towering, crumbling spires create a desolate landscape. Bitter brine-filled oceans surround the cracked plains, harboring monstrous sea creatures that lurk beneath the icy surface. Volcanic vents sporadically spew spiteful fumes, adding to the oppressive atmosphere, while brine corrosion threatens the unwary. The presence of Demogorgon can drive any mortal to madness, and the fierce inhabitants protect their dark lord's palace with sinister ferocity.
