Calast, situated within the Calast system, functioned as a space station for civilians located in the Golan Space Colony 2.
Following the Battle of Hoth, Rebel forces launched an attack on the Imperial Dreadnaught-class heavy cruiser known as the VTR-LX. This assault occurred while the cruiser was in the process of refueling at the Calast station. The VTR-LX was in transit, carrying prisoners captured from Echo Base and destined for the Bundil II station.
