After two centuries of conflict, Humankind's three races - the Progen, Terrans and Jenquai - had achieved an uneasy balance of power by dividing known space between them.

The Terrans claimed Earth, headquarters to their massive trade corporations. The genetically engineered Progen, bred for perfection, commanded the wastes of Mars. And the Jenquai, ever seeking knowledge, created great space stations to orbit the moons of Jupiter.

when the first stargate, an ancient artifact built by an unknown people, was discovered. Coveting its secrets for their own, the Jenquai hid the Gate from the other races. But their efforts were in vain; within months, a spy employed by the Terran conglomerate InfinitiCorp revealed the Gate's existence to the outraged Terrans and Progen. Humanity was suddenly thrust into conflict, an epic battle over control of the Gate.

The three races fought a devastating nine-year war, dubbed the Gate War, using weapons far deadlier than any previously conceived. Millions of lives were lost, and millions more would have perished had the Terrans not surprised their foes with a sudden cease-fire proposal. After months of negotiations, the three civilizations agreed to share the Gate, and declared an uneasy peace.

However, InfinitiCorp had plans of its own. Under utmost secrecy, its scientists had reverse-engineered the Gate's technology, and within a few short years the mighty conglomerate announced to the astonished worlds the genesis of the Infinitigate.

Fifty years have passed since the invention of the Infinitigate. Progen, Jenquai and Terrans alike have thrived, spreading their civilizations across a dozen star systems, exploiting their riches. However, though the races are at peace, acrimony remains. Tension and distrust govern galactic relations and every citizen fears the day when the spectre of war again raises its shadow.

Something else, something even more frightening, clutches at the minds of the humans. The aliens who built the Gate -- aliens with clearly superior intelligence and technology -- have yet to appear. Where did they go? Will they be coming back? And will they be pleased to find an upstart Humanity colonizing what once belonged to them?

The next chapter in human history is about to begin, and you will play a pivotal role.
