This looks rather interesting I must say. I am definitely watching how this develops. 
I also have an initial idea of a form of tribal warrior-regiment that has ties to The Shadow Realm to empower them, with a focus on swiftness, agility, and religious empowerment through their tribal body markings and the connection the other realm, however, they are "pre-alpha" thoughts as of right now - hopefully it is decent and acceptable ^^

Would you mind explaining me the different races available? Or can we make them up ourselves?
