Malbolge is the sixth layer of Hellmar. It is not a pleasant place.
From Mimir.net: "The Hell of Sloth, where petitioners are punished for laziness in their past lives, and baatezu who are caught breaking rules are imprisoned. Malbolge has been submerged under the gory remains of its former Lord, now splattered across the layer in rotting, semi-alive, and fully ravenous, chunks. Themes of body horror, constant struggle to avoid being consumed, and perpetual vigilance to avoid being crushed."
