Orion System is the farthest human world discovered under Project Far Star. It was on this fledgling frontier planet that Humanity encountered the Vanduul for the first time. On August 9, SEY 2681, a Vanduul raiding party struck a main post on Armitage. Subsequent raids occurred over a scattered number of years, the Messers began to treat this new alien as a mere annoyance. In 2712, that changed in what became known as the Battle of Orion which resulted in the UEE's abandonment of the system.
