Hell

Overview
Most people believe that hell is the place where the souls of evil people go when they die. There, those souls are tortured for the rest of eternity by demons. Those beliefs are somewhat correct. There are no "souls of the damned", instead, the souls of those who make deals with greater demons are sent there. The purpose of these souls is discussed below.

The Structure of Hell
Hell is not one singular location, but instead, it is split up amongst 7 "layers", each with its own purpose and terrain. Little is known about the physical makeup of each layer, as such, there are no reliable maps of any of the layers, at least none made by anything other than a demon. Each layer is ruled by a demon lord appointed to that position by Lucifer himself.

Avernus
Avernus is the first layer of hell. It is the easiest layer to access from the earth. It is the training ground for hell's armies. It is largely flat and dry like a desert.
