There are several types of different Demons that you can play on this site
However they all have different rankings within the circle of Hell itself, so, here is a list of how things are ranked in order to make things a lot less complicated for people who don't know
These are the lowest form of evil that can come out of Hell, these can be pretty much anything from over sized cockroaches, to Succubus and Incubus however it is important to note that whatever form your demon takes, it will not be anywhere near as powerful as the other rankings of demons that occur above them. There are unlimited numbers of demons available to RolePlay as.
These types of demons are Angels that have been tempted by Archdemons or other forms of evil, and have fallen from their status of Angels, these have a duty to guard the city of Dis, which encompasses the lower circles of Hell, and are ahead of the ordinary demons in terms of rank. There are unlimited numbers of demons available to RolePlay as, although it is important to note that in this RP Satan is NOT classed as a Fallen Angel.
These are the equivilant of Archangels, and there is one Archdemon to each circle of Hell, where it will take residence and preside over the other demons who live there. There are only nine Archdemons that will be able to be played in this RolePlay, and these demons are in control of the lower ranks, they form the Leaders if you will to the Armies of Hell that are attacking the humans left on Earth.

And The Morning Star - The Punished now trapped in the Ninth Circle of Hell.
