Chen Yan travels between worlds, ending up becoming an honorable prince in a medieval fantasy world. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land.

Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders coming from the realm of evil.
