Owen Nakai, a gamer at heart, is an engineer working with an Egress device, portal technology that has revolutionized the 22nd century, when a mishap transports him and his sister, Faye, to another version of earth. An earth ravaged by the gods. Used as a staging ground to raise champions to fight off an unknown darkness and then abandoned, left to the devices of power beings called Eidolon Sovereigns.

The siblings are separated after leaving the portal at different points and if Owen wants to find Faye, he will have to adapt to this strange new land or perish. Through fortunate happenstance, Owen mantles the power of a long dead Eidolon and becomes a Sovereign.

With only a fleeting glance at a walled city where Faye ended up, Owen, with the help of a loyal servant of the Eidolon he mantled, makes for Bathurst, the last human city. But his new power brings new enemies and rivals that seek to steal the mantle from him.
