Magic binds worlds no matter how far apart they are. The kingdom of Esparia  is the nexus of interdimensional travel for humanity in every universe. Valen Esparia, a brilliant and eccentric court wizard, and the king’s middle progeny, has the power to traverse realms at will. Caught off guard in a sudden attack from a neighboring kingdom, he finds himself banished and cursed to doom every world he sets foot in. With his sister caught in the crossfire, and the well of his own mana dwindled, he embarks on a journey where he must lift his curse, resurrect his sister, and save every world he travels to.
