A year had passed since Jordan Cross joined the Green Lantern Corps. Since then he had been traveling through time and space fighting a galactic battle against the Zamarons.

One week after
Clark sent his message to Jordan, Clark received a message from the Corps. The Corps had lost contact with Jordan's battalion. The battalion was chasing a horde of Zamarons though a time portal, one that lead to earth--an earth thirty years in the future.

The Corps later intercepted Zamaron communications hinting of a legion of enemies waiting for them on the other side of the portal, a great weapon that would finally give the Zamarons their victory, and an evil genius who would lead the Zamarons into a new era.
