A brief battle happened aboard the Radiant IX starship, which was located on the Poison Moon asteroid within the Hoth system. The combatants involved were Jedi Knights Et Rex and Obi-Wan Kenobi, along with Jedi Padawan Anakin Skywalker, who faced off against the Dark Jedi Alysun Celz. Following the engagement, the Jedi subdued Celz, who was subsequently transported to Coruscant to be judged for her offenses.
