I am actively promoting and RPing this ingame but i'm also leaving some information here for anyone interested to roll a character.
In sort, devil pacts, deals, contracts and all sorts of stuff that has to do with devilry.
There is more than meets the eye to the plotline and goals that can't be explained in an OOC post.
For more information on Fierna (Lord of the Forth Layer of Hells)
