Description

The Demogorgon is chaos and destruction made flesh—a towering, reptilian demon with two simian heads, writhing tentacles for arms, and a madness that infects all who witness it. Each head is its own mind—Aameul and Hethradiah—locked in eternal conflict, yet bound within one body. Its presence warps reality and drives mortals mad.

Demogorgon is known as the Prince of Demons, ruling over the layer of the Abyss known as Ghehena or the Gaping Maw.
