Each millennium, the great Leviathan emerges from the depths of the sea in order to curse the world that he now doesn’t recognize. By sending the world into monochromatic chaos, he can concentrate on his dark plans while panic sets in. Through exploration of a vast unknown world, Billy, a fisherman’s child who carries a heart filled with color, will capture and befriend strange creatures in a coming of age tale, each with their own strengths and weaknesses, so they can help fight the Leviathan, rebuild the village of Star Harbor and bring back color to the realm!
