The others came for Heinrich Aguirre when he was a child. Born in one of the Germanies with a light inside his mind, Aguirre is raised to take his place as one of the Magian, the rare few who can part the veil between the many versions of Earth. Vowing to protect these endless worlds and all who live in them, Magian do not hesitate. But during his first battle, while still less than a man, Aguirre does, only to see the magus who raised him die instead.
For his sin, the others banish Aguirre to the solitary path.
Seventeen years later, Magian are being slaughtered, and with a kind of power no magus has ever seen before. Suspicion quickly falls on Aguirre, who realizes that his only hope is to find the truth himself. So Aguirre turns his back on those who have already turned their backs on him, and with the Magian in pursuit, he races to save his own kind before they kill him first.
