Koa: The fight begins!

In the world Koa, there was only peace and tranquility. 13 out of 14 races lived in harmony and seclusion. That is until the Arakai, a tribe of darkness that found leadership in a dark spirit from the darkest place the world has ever seen, the Void, took over searching for complete power. First they took the Ejon tribe to break the balance of light and dark. The world collapsed falling under the rule of the Arakai and their leader. The races were enslaved and few escaped from capture. The Arakai suppressed the worlds power and started killing what didn't die from sickness. What was left of the races that weren't captured formed the rebellion and started to free prisoners from the camps and formed an army.
