Canyon, situated close to Moorja in the Expansion Region, was a planet characterized by dry, mountainous terrain and extensive plains.
An Imperial Victory-class Star Destroyer inadvertently stumbled upon the planet when it crashed into an adjacent asteroid. Despite this discovery, the Empire disregarded Canyon. However, the Star Destroyer's emergency beacon drew the attention of pirates under the command of Guldus Bemm. These pirates established a mining colony on Canyon, exporting valuable ores that were utilized in the manufacturing of starships and electronic devices.
Not long after the Invasion of Bakura, Canyon became the location of a failed scheme to lure Luke Skywalker with the false promise of a crystal-filled cave, supposedly containing materials ideal for lightsaber construction. This trap did not work on Skywalker. Instead Platt Okeefe, a smuggler, was apprehended by Imperial Advisor Bregius Golthan. Okeefe had been on Canyon to negotiate mineral rights with the local government on behalf of the New Republic. The pirates maintained their dominance over Canyon long after the Battle of Endor.
