Andross must master magic to help him carve a path to greatness.

Andross has other plans, preparing to travel with his friends to the city of Gesti Sky. There, he will find the answers he seeks and more, even if it means confronting an immortal household that has reigned over the world for a thousand years.

With both his, and the lives of his friends in the balance, Andross' only chance of survival may be revealing his greatest secret to the world.
