The planetoid once held a Rebel comm center that was wiped out by Imperial stormtroopers led by Kyle Katarn. It was here that the cadet Katarn first met Jan Ors and spared her life. Four hundred thirty-six Rebels, and all but six of a platoon of stormtroopers, died in the fighting. Although Katarn's troops suffered heavy casualties, and Katarn himself was seriously wounded, he emerged victorious and was celebrated as an Imperial hero. During his graduation ceremony at the Imperial Military Academy at Cliffside, Katarn was awarded the Medal of Valor by Jerec for his actions during the Battle of AX-456.
