Malbolge

Malbolge, the sixth layer, has outlasted many rulers, among them Malagard the Hag Countess and the archdevil Moloch. Malagard fell out of favor and was struck down by Asmodeus in a fit of pique, while her predecessor, Moloch, still lingers somewhere on the sixth layer as an imp, plotting to regain Asmodeus’s favour. Malbolge is a seemingly endless slope, like the sides of an impossibly huge mountain. Parts of the layer break off from time to time, creating deadly and deafening avalanches of stone. The inhabitants of Malbolge live in crumbling fortresses and great caves carved into the mountainside.
Malbolge’s current archduchess is Asmodeus’s daughter, Glasya. She resembles a succubus with her small horns, leathery wings, and forked tail. She inherited her cruelty and love of dark schemes from her father. The citadel that serves as her domicile on the slopes of Malbolge is supported by cracked pillars and buttresses that are sturdy yet seem on the verge of collapse. Beneath the palace is a labyrinth lined with cells and torture chambers, where Glasya confines and torments those who displease her.
