The Old Republic first established a small base on Borleias for the purpose of plotting runs to the Corporate Sector and elsewhere. The Alderaan Biotics hydroponics facility, a producer of Alderaanian foodstuffs, was also built on Borleias' far side, but over the years it was abandoned and left to the care of maintenance droids. The Empire eventually took control of the Republic base, adding shields, ion cannons, and TIE squadrons for its defense. The installation's commander, General Evir Derricote, also discovered the forgotten Biotics facility and made it profitable once more, while secretly siphoning Imperial credits and resources to make his headquarters more powerful and secure than it would otherwise appear to be. Because of the Pyria system's close proximity to the galactic core, the Rebel Alliance chose to capture Borleias and make it their key to hitting Coruscant, some three years after the Battle of Endor. During their first attack, however, the Alliance greatly underestimated the defensive strength of the Blackmoon installation and were soundly defeated. On the return mission, Rogue Squadron pilots torpedoed a power conduit at the end of a rift valley to help bring down the base's shields, while a commando team captured the facility from the ground. This attack was a success, and Borleias became the new operations and staging base for Rogue Squadron.
