Cantros 7 was a planet located within the Outer Rim of the galaxy. The world was inhabited by a species of sentient felinoids who joined the Alliance to Restore the Republic during the Galactic Civil War. Having been ignorant of the defeat of the Galactic Empire at the Battle of Endor, two separate Rebel cells that had been established there believed they were continuing to fight the Empire, not realizing that they were actually fighting each other as a result of being duped by Lumiya. Luke Skywalker eventually succeeded in exposing the truth to both sides.
