Dis
Dis, the second layer of the Nine Hells, is a labyrinth of canyons wedged between sheer mountains rich with iron ore. Iron roads span and wend through the canyons, watched over by the garrisons of iron fortresses perched atop jagged pinnacles.
The second layer takes its name from its current lord, Dispater. A manipulator and deceiver, the archduke is devilishly handsome, bearing only small horns, a tail, and a cloven left hoof to distinguish him from a human. His crimson throne stands in the heart of the Iron City of Dis, a hideous metropolis that is the largest in the Nine Hells. Planar travellers come here to conspire with devils and to close deals with night hags, rakshasas, incubi, succubi, and other fiends. Dispater collects a piece of every deal through special provisions that are added to contracts signed on his layer of the Nine Hells.
Dispater is one of Asmodeus’s most loyal and resourceful vassals, and few beings in the multiverse can outwit him. He is more obsessed than most devils with striking deals with mortals in exchange for their souls, and his emissaries work tirelessly to foster evil schemes in the Material Plane.
