Malbolge

Malbolge

There is significant disagreement between cosmologies on the nature of the sixth circle of the Nine Hells. As a Great Wheel layer, Malbolge was a gargantuan tumble of angular black stone blocks, each block ranging in size from a small city to a large metropolis, that formed a pile hundreds of miles thick. The randomly tilted and ill-fitting blocks were honeycombed with angular passages and caverns causing non-flying travelers to frequently need mountaineering skills and risk avalanches. Stinking clouds of vapor rose up from the depths and lit the sky with the color of blood, causing cosmologists to speculate that the blocks of Malbolge may have rested on an infinite sea of lava. Corroborating reports have been heard of flammable materials left on the ground spontaneously combusting. Most habitations in Malbolge were copper-clad fortresses built from black stone.
The World Tree view of this layer was similar to the Great Wheel plane of Gehenna: a steep, infinite craggy incline often subject to avalanches that crushed most anything that got in the way. The copper-shod redoubts were teardrop-shaped or otherwise engineered to deflect tumbling boulders, but even those could not long withstand a direct hit from a major avalanche.
In the World Axis cosmology view, Malbolge is another huge cavern connected to Stygia by icy canals that run hundreds of miles before reaching their destination. A former godly inhabitant has shaped the realm into a vast garden with fountains, towers, reflecting pools, and all manner of landscaping delights. With the coming of the devils, Malbolge was still beautiful on the surface but creeping corruption permeated the realm, twisting the beauty, perverting the architecture, and poisoning the pools.
