Ok, I'm new to this so don't expect much but, basically there are 6 different clans of demons, each hold two types of magic, Shadow Clan(Shadow and Lightning), Light Clan(Light and Ice), Blood Clan(Blood and Fire), Earth Clan(Earth and Metal), Flow Clan(Water and Air), and the Nature Clan(Nature and Animal). There are different states that the demons can be in as well, Primal or Natural(Hybrid of Animal and Human, the animal being their spirit animal), Animal, Human, and Enlightened(Basically like becoming a super powerful version of their spirit animal but still with human qualities, the looks of this is left to your creative minds to decide and describe). All demons can only control one of two magics from their clan, if any.You are also allowed to be human, humans do not get the awesome transformations, but they do get to control two different magics, as long as they are from two different clans. Most humans can't see the demons roaming the earth nor can control magic, but a few (No, you are not chosen ones, you just get lucky, or it may be genetic) are blessed (or cursed, depending on how you look at it) with the sight and can see the world around them, and the challenges that the good demons face to protect humanity from the bad ones.
