Eight Hells

The Eight Hells (also called Infernus, the Planes Below) are eight connected planes that are inhabited by devils, the souls of the damned, and all manner of infernal creatures. Though they vary widely, the planes are all dreadful domains of eternal torment.

Each of the Eight Hells is ruled by an archdevil. The extent to which each archdevil is in control of their domains varies, where some run totalitarian governments with an iron fist and others rely on reputation and sheer power to maintain control.

The planes of the Eight Hells are organized not as layers but like spokes on a wheel such that each plane is adjacent to two other planes.

Avernus
Avernus is a barren wasteland, covered in broken weapons and bones. Avernus is ruled by Bel the Warlord, greatest of pit fiends and commander of the most organized army in the Planes Below.

Avernus has borders with both Cania and Dis. Bel maintains relationships with both planes, but is careful not to become embroiled in their growing conflict with the rest of the Eight Hells.
