Past

50 years after the third world war, the seven founding fathers created the United Earth Republic, thus having every Earth nation under one banner.
With great efforts, Earth began the colonization and terraforming of Mars, as well as looking for ways out of the solar system.
Deep space scans revealed an anomaly close to Jupiter's orbit. This anomaly has proven to be the first naturally-occurring wormhole. By researching this wormhole, scientists have discovered that it can be used to travel faster than light between two points in space.
Humanity was united more than ever with this discovery. Millions of people set out to make their lives better into the unknown, away from the desolated Earth.

Present

100 years have passed since the first wormhole was discovered. A lot of planets have been explored and colonised, wormholes to new systems are charted by the deep space expeditionary forces, and everything is quiet... or so it seems.
