Hell consists of nine distinct realms, each being commanded by a demon major, more commonly referred to as a Prince of Hell.
Aside from the demons born here, the souls of mortals can also be found in Hell, as they are its primary resource. Most souls are condemned to an existences of unrelenting torture. However, others are twisted and reshaped to suit the needs of Hell's demonic inhabitants. Mortal souls can be corrupted into—but not limited to—machines of war, beasts of burden, building material and other constructs.
