Avernus

Avernus was the first layer of the Nine Hells of Baator. The most likely beachhead for any attack by demon-kind, it was the primary battleground of the Blood War: legions of devils marched across its plains in continual readiness to repel the hordes of demon invaders that sailed the River Styx into the layer.

Avernus welcomes all. — Geryon, repeating an old saying

Geography

By all accounts Avernus was a desolate wasteland with rocky terrain, sparse, twisted vegetation, concealed snake pits, caves and warrens, volcanoes, and rivers of magma. The sky was starless, full of choking smoke, and glowed a dark red due to balls of flammable gas that floated about or streaked across the atmosphere, randomly exploding as a fireball. During the Blood War, Avernus echoed with the marching of legions of devil troops preparing for the next campaign against the demons of the Abyss, the ground was littered with the detritus of countless battles, and blood trickled out of the ground in vein-like streams eventually flowing into the river Styx.
