Avernus

No planar portals connect directly to the lower layers of the Nine Hells, by Asmodeus’s orders. As such, the first layer of Avernus is the arrival point for visitors to the plane. Avernus is a rocky wasteland with rivers of blood and clouds of biting flies. Fiery comets occasionally fall from the darkened sky and leave fuming impact craters behind. Empty battlefields are littered with weapons and bones, showing where the legions of the Nine Hells met enemies on their native soil and prevailed. The archduchess Zariel rules Avernus, supplanting her rival, Bel, who has fallen out of Asmodeus’s favour and is forced to serve as Zariel’s advisor. Tiamat, the Queen of Evil Dragons, is a prisoner on this layer, ruling her own domain but confined to the Nine Hells by Asmodeus in accordance with some ancient contract (the terms of which are known only to Tiamat and the Lords of the Nine). Zariel’s seat of power is a soaring basalt citadel festooned with the partially incinerated corpses of guests who failed to earn the archduchess’s favour. Zariel appears as an angel whose once-beautiful skin and wings have been ruined by fire. Her eyes burn with a furious white light that can cause creatures looking upon her to burst into flame.
