I am working on a few stories now. If any of the mythology used confuses you, refer here.
Abyssian: One who hails from the Abyss. One can tell them by their red eyes and Black hair. they have three gods, The Mother, the Knight, and the Dread. Also, Abyssians can become wolves or ravens if needed. Zeta and Theta are the exeptions, as the become kitties.  Also, Abyssians are rather violent at times, letting their weapons speak for them. 
Guardian: element weilders of great strength. marked by golden eyes or odd weapons. 
Denro: the opposite of abyssians, these are a peaceful group, marked by powerful spells and purple eyes

Yeah, i should mention this mythos is all from my head, so message me if it is confusing.
Also, I will use curse words in both modern and old meanings, so you are warned. 
I may get a book done sometime, who knows?
