Beneath the darkened catacombs and caverns above lies an ancient and monstrous thing waiting in the darkness for its prey to come down and enter its eternally ravenous corpus where it will devour them and slowly digest their souls.
The lowest levels of the Underdrake are entirely comprised of this massive entity from The Umbral. It is not just in the Underdrake, but is the Underdrake; a sentient and maddening maze that spans many worlds.
Throughout the forbidden pages of eldritch grimoires and inscribed on crumbling and cursed scrolls, Umbraxas is known by many fearsome epithets:
- The God of the Labyrinth
- The Thousand-Mouthed Maze
- The Writhing Dark
- The Endless Hunger Below

It sounds evocative, and darkly fascinating.
