@Montezuma II, you came to the right place
Initially, Korba wanted the Kamal to be human-ish with a strong nomadic element to them. The "snow demon" aspect of them would be based on their reputation, similar to the Vikings I suppose. This would also explain their seasonal raiding. Yet leaving them to be just nomads doesn't do justice to the Kamal and the mysterious continent they come from.
After some discussion, we came up with the current Kamal who are humanoid, and appearance wise human, and certainly interbreed-able with most humans but there is more than meets the eye aesthetic to them. Similar to their neighbors the Tsaesci, there is more going on with these raiders, their motives and cultural goals. If you look at their priest (shaman) headgear, the Kamal seem to have their own unique magic focus, inspired by their harsh elemental surroundings . As we develop them more, we hope to bring the players more glimpses of this.
Stylistically speaking, the Kamal are based on a combination of Maori (with their elaborate mystical body tattoos), and Siberian nomads. Their head dresses are elaborate and fear inducing playing up their horned demons reputation with anyone who encounters them.
All Akavir are heavily East Asian based - the Tsaesci being a refined combination of Japanese and Chinese (visual) and Indian (magic, practices), the upcoming Po Tun a combination of early Han Chinese and Tibetan, and the Monkeymen a combination of South East Asian and Indian.
Feel free to ask away!
