A land divided by hate and ravaged by war is home to six different races. The mightiest two were banished, one to an island high in the sky, the other to a hellish realm known as the Underworld. The race in the Underworld, the demons, revolted, created a destructive and horrible war; one that nearly destroyed the world. Eventually they were beaten back and sealed away, preventing future attacks. Things remained this way for three thousand years, until a young warrior on the sky island fell off.
