Celsor 3

This ice moon was located in the galaxy. Its primary terrain was ice pillars. After its departure from the Ileenium system, the supertanker fuel depot Colossus passed near it. New Republic and Rebel veteran Jarek Yeager chose it as a location for training exercises after being placed in command of the Ace Squadron, the platform's main defenders. During the training exercises, the Aces were attacked by a giant ray awakened by their flying through the pillars, and Yeager was nearly eaten before the Aces managed to shake his starfighter free by shooting one of the pillars so it collapsed onto the creature.
