The Forgotten Realms [Fan Version]

Avernus, the first layer of the Nine Hells, is a desolate, volcanic wasteland eternally scarred by war and the infernal machinations of the devils. The landscape is a chaotic mix of obsidian cliffs, fiery rivers of lava, and sulfurous swamps, where the air hangs thick with the stench of brimstone and decay. This infernal realm is a constant battlefield where the legions of Asmodeus, the archdevil of tyranny, clash with hordes of demons and rebellious devils, a ceaseless war for control of the infernal landscape. A network of crumbling fortresses and twisted metal structures dot the landscape, reminders of a war that has raged for millennia. In the heart of Avernus lies the Blood War, an endless conflict that has spilled over into the mortal realms, a ceaseless struggle that permeates the very air of this infernal layer. Entering the this plane is impossible without using magic that allows you to traverse different planes of existence.

The sky is a perpetual shade of crimson, with dark clouds swirling ominously. Jagged mountains rise in the distance, and the air is thick with the stench of sulfur and despair.
