Demons

Demons are a creature type and the Hell main inhabitants - despite there are other creatures living there-. They born after the defeat of the Morning star and its army. There are three main demon families.

Lore
The Fallen Angels became the first demons when the pain and illnes devoured by Tartarus reached the Hell and torned them up. Their purity and several abilities were partially or totally removed. Lucifer's and their commanders pride insisted creating a hierachy, giving Lucifer the Great Prince title.

The hellborns demons were made by the Fallen Angels as an attempt to take over the Hell's outer regions. They were conceived when Lucifer's lutenants found several passages across the Veil of Angels. They weren't able to go through them because of their inmensity. The hellborns are smaller in power but crueler and more violent than Fallen Angels (as they never knew the kindness of the good days).

Corrupted souls are the third and lesser class of demons. They are pulled downstream from Hades by the Styx. They're souls who made several deals with demons. They suffer Hell's agony and illness. They became violent and always try to scape from hell seeking some relief in the outer world.
