In the world of Erathia, centuries of war between humans and demons have left the land weakened and the human king a prisoner of the demon armies. A young warrior named Ewan is sent to find and free him by a nobleman named Mendes. Along the way he is joined by Lorean, an elven archer, and eventually by Kayn — the captain of a mercenary company called the Unicorns, later revealed to be half-demon, with no loyalty to either side. The demon lord is confronted, escapes, and must be pursued. Mendes later tries to expose Kayn's nature to secure his own position; Kayn deals with Mendes. Ewan refuses to continue alongside Kayn and the two part ways. A year later, with Kayn arrested and badly wounded, Lorean asks Ewan to help rescue him. They find the demon lord waiting. Ewan kills the demon lord and a three-headed dragon. The conflict ends. Kayn apologizes.
