In the year 18 BBY, following the ambush near the Twins, the Galactic Empire apprehended Thi Xon Yimmon, the Cerean chief of the Whiplash resistance group. Subsequently, Vader imprisoned Yimmon within the Kantaros Station, which was secured by an Inquisitorius force under the command of Probus Tesla.
Nevertheless, information regarding the prison's whereabouts quickly spread among the criminal network and then to numerous resistance combatants. Consequently, two plans for a breakout were initiated: one by Whiplash operatives Den Dhur and I-5YQ, and the other by Antarian Ranger Sacha Swiftbird, disguised as Black Sun associates, in addition to a separate plan by Jedi Knight Jax Pavan.
During the conflict, Sacha eliminated Probus, thereby rescuing Pavan, and Pavan himself engaged in a duel with Darth Vader. Ultimately, Yimmon was successfully liberated, and all resistance fighters managed to flee the space station.
