The Prince of Demons; Ahmon-Ibor; the Sibilant Beast; Siosivash
Planar tanar’ri lord of insanity [he/him] / CE
Lair: Abyss / Layer 88 — The Gaping Maw
The two-headed Demogorgon rules over the Gaping Maw, the 88th layer of the Abyss, from their fortress Abysm. The first demon to be shaped from mortal souls and emotions, Demogorgon is far older than their chief rivals for the lofty title of Prince of Demons, Graz’zt and Orcus, with whom they are engaged in a cold war to determine who the most powerful demon in the Abyss will be. Unstable, violent, and filled with spite, Demogorgon makes allies rarely and enemies easily.
Were it not for their sheer seniority and the power they hold through the mantle of Prince of Demons—as long as they hold this title, there can literally be no single demon more powerful than Demogorgon—they would surely have been toppled long ago. They have cultists on the Material Plane, but rarely humanoid ones—Demogorgon invades the dark dreams of creatures such as kuo-toa, ixitxachitls, and troglodytes. They have a mutual understanding with the obyrith lord Dagon, who offers counsel and lore to support the twisted machinations of the Prince of Demons. The terrible truth of Demogorgon is that each of their heads has its own personality, and that the two are at war with one another. The left head, Aamuel, is charismatic and calculating; the right head, Hethradiah, is feral and destructive. The only thing the two heads absolutely agree on is that this secret must never be revealed.
