In 1972, an ancient alien hypergate was discovered on the surface of the moon. Using this technology, humanity began migrating to Mars to settle there. After settlers discovered additional advanced technology, the Vers Empire was founded, which claimed Mars... and its secrets, for themselves. Soon after, the Vers Empire had declared war on Earth. In 1999, a battle on the Moon's surface caused the hypergate to explode, shattering the Moon, and scattering remnants into a debris belt around the planet. Cut off from Mars, the remnants of the Vers Imperial Army built several massive orbital space stations within the debris belt and a ceasefire was made. 15 years later, an attack on the Vers princess during a peace mission causes the Empire and its 37 clans of Orbital Knights to launch a new attack on Earth, this time determined to conquer it once and for all.
