The Rosh System is significant for its multiple trading outposts on the moons orbiting Rosh 3. While it is most applauded for is vast and complex facilities for loading and unloading raw materials, it is similarly dedicated to being a crossroads of culture from the Exodian Sector, Graad Ak Sektor, and the Fjotmor Sector.

Historically, it is also the site of the Battle of Rosh which ended the War for Private Space. The UPS were in the process of constructing a castle station to protect the system and prevent further incursion. However, the majority of their fleet was deployed in the Slaegtaf and Ahntornus system. Seeing a weakness, the SCO launched an assault on Rosh, finding a vulnerable station and a scattered defending fleet of smaller corvettes. Assuming that the corvettes would flee or else be demolished by the SCO's long-range weapons on approach, the fleet assumed a tight formation and prepared to bombard the UPS forces. However, the UPS corvettes were able to use a combination of complex gravity assists to approach the invading fleet with little engine signature, and at the last moment, accelerate with a technique now known as stoking, bringing them within point-blank range before the SCO could react. Not expecting to engage so soon and at close range, the SCO fleet were in for a second surprise, as the Union corvettes, instead of opening fire chose to ram instead. At that time, prevailing starship design among the SCO was to avoid collision altogether, so the far more durable Union ships were able to cause massive hull damage while sustaining little damage of their own. The SCO ships, already in a tight formation, collided with each other, compounding the damage. In the end, only two Union corvettes were lost, while the entire invading fleet was destroyed. Shortly after, the war was ended.
