Originally from Atlantis, the Gods have been fighting in a rebellion of human slaves against an immortal alien race known as the Korantians and their human allies, the Harrapans, for thousands of years! Allied with the Nazcan people, a group of rebellious humans from South America, the Gods have been seeking a strategy to defeat the Korantians.

When their Fleet arrives, the Korantians intend to conquer earth, eliminate most of its human population, and enslave the rest. The rebellion has been kept secret from the earth's population by the Korantians and the Atlanteans, each of which has been secretly trying to manipulate the rest of the human societies of earth to enable the development of the planet's infrastructure.
