The Choah Belt was a field of asteroids situated within a sector located in the Outer Rim Territories. During the time of the Galactic Civil War, the Rebel Alliance's military established a fuel refinery amongst the asteroids. Around the time of 0 ABY, not long after the Battle of Yavin, the Galactic Empire discovered the refinery and proceeded to destroy it in a battle, which resulted in significant fuel shortages for the rebel forces spread throughout the sector. Sometime following that battle, the Rebellion stole the Empire's Field Secured Container Vessel, the Black Ice refueling ship, as compensation for the loss of the refinery.
The Choah Belt was first presented within current Star Wars canon in the thirty-fourth issue of De Agostini's magazine series, Star Wars: Build the Millennium Falcon, which was released around August 26, 2015. In the Star Wars Legends continuity, the Choah Belt initially appeared in Black Ice, a 1990 Star Wars: The Roleplaying Game adventure by West End Games, authored by Paul Murphy and Bill Slavicsek.
