General Karastace Gonn was a Human male who fought for the Galactic Republic as a General in the Great Galactic War against the reconstituted Sith Empire.
In the course of the Great Galactic War, Karastace Gonn proved to be a persistent obstacle for the Empire, thwarting their efforts to seize control of outlying star systems.
Early in the Galactic War, at a clandestine location on Nar Shaddaa, Karastace had been working to recruit members of Imperial Intelligence to betray the Empire and join the Republic. Although Gonn achieved some success, Darth Baras discovered that Gonn planned to rendezvous with some of these defectors on a certain moon. Consequently, he dispatched his apprentice to eliminate both Gonn and the Imperial double agent Fawste. In the ensuing confrontation, Gonn and his soldiers battled the Sith Warrior, but they were ultimately killed.
