Fort Sunfire was one of the two primary installations for the Galactic Empire's Imperial military on the desert planet of Tatooine during the time of the Galactic Civil War. The other installation was Fort Ironhand, which was situated near Anchorhead. Specifically, Fort Sunfire was located in the Desert Valley, to the south of the city of Bestine.
Not long after the pivotal Battle of Yavin, a Rebel operative obliterated the base as part of a series of operations carried out on Tatooine. The destruction of Fort Sunfire triggered a localized skirmish between Captain Kosh and the Rebel forces in the area.
The fort was reconstructed at some point prior to 3 ABY. In that year, Kay Vess, accompanied by bounty hunter Vail Tormin, managed to infiltrate Fort Sunfire. Their mission was to locate an Imperial file that would reveal the identity of a Zerek Besh spy who was operating within Jabba the Hutt's palace.
Fort Sunfire makes an appearance in the 2014 Canon mobile game titled Star Wars: Commander. Within the Rebel Alliance campaign of the game, it is Saponza's partner who is responsible for its destruction.
The concept of Fort Sunfire originally appeared in a supplement published by Wizards.com for the Star Wars Roleplaying Game. This supplement was made available on November 11, 2004.
