Balmorra
Balmorra is a rocky, barren planet with many canyons in the Core region of the galaxy. The Galactic Empire used this planet as the site for many of its factories supplying AT-AT and AT-ST walkers as well as TIE fighters, mostly hidden within the canyons of the planet. Because of the heavy industry, the planet has been heavily polluted and the sky is thick with smog and pollution. This planet is featured in the video game Star Wars: Rogue Squadron.
After the death of the Emperor at the Battle of Endor, Balmorra revolted successfully, but when the Reborn Emperor launched his initial offenses during the events of the Dark Empire saga, Balmorra fell again under the Imperial fist. After the Emperor's second death, Balmorra revolted a second time, whereupon it was attacked by Military Executor Sedriss; Sedriss lost the battle as even his shadow droids could not defeat the new battle droids the Balmorrans had developed, the SD-10 battle droids and the new X-1 Viper Automadons. In exchange for the droids, Sedriss signed a peace treaty with Balmorra, granting it independence.
