When the Xenoid threat was discovered, human society was thrust into an era of martial law. Security became top priority, at the cost of individual liberty.
In the face of this growing oppression, many left their homeworlds in search of freedom. The Freerunners fled, to explore and settle the new frontier planets.
When Enforcers from the homeworld pursued them in a military effort, the Freerunners were forced to defend themselves. This was the beginning of the great human civil war which continues to this day.
In hope of defending your settlements against threats, both human and alien, you have enlisted as a pilot with the Freerunners.
