This article is about A layer of the Nine Hells of Baator. For other uses, see Avernus (disambiguation). The first layer of Baator is a wasteland of charred, rubble-strewn plains, with mountains and talus-sided foothills breaking up the monotony. Legions of mail-clad devils are on perpetual watch here, always assembling for some new cross-planar Blood War sortie.
Blood-red light suffuses the air, and fiery balls flit randomly across the sky, sometimes detonating to terrible effect.
Blood and viscera coat the entire surface of Avernus. That lump underfoot might be a rock, or it could be a stray bit of bone or horn ripped from the body of a devil or a demon. Runnels of blood flow in streams across Avernus, finally joining the River Styx. Toothy mountains loom on every side, offering fatal obstacles to those unwise enough to scale them, and sharp edges of crystalline rock tear at flesh and clothing.
