The first gloom of Hades is a land of stunted trees, roving fiends, and virulent disease. But more than anything else, it is a plane ravaged by war. This is the central battlefield of the Blood War. Fiends, warrior-slaves, trained beasts, and hired mercenaries gather here to wage horrific battles on an epic scale. These battles despoil the already bleak terrain. The sounds of rending claws, clashing weapons, and screams echo across the entire layer.
