>Avernus, the First Hell
The first layer of the Nine Hells is Avernus. It is the
surface of Baator’s ruddy orb. It is a desert of stone, pumice, and ash broken by the occasional range of low, jagged mountains or a flowing river of lava. Unlike the deeper hells, Avernus has a sky. In the sky, sullen, roiling clouds of red and black constantly flicker and burn with gouts of orange flame. The air is hot, dry, and acrid, fouled by volcanic fumaroles.
