The Liberty served as a capital ship within the fleet of the Yevetha belonging to the Duskhan League. This vessel was utilized throughout the devastating Great Purge which transpired during the years 16-17 ABY.
Liberty, alongside Honor, and the Star Destroyer flagship Devotion of Yevetha, was one of the Yevethan warships deployed to attack Polneye as the Purge began. Through orbital bombardment, she obliterated the settlements known as Eleven South and Eleven North, in addition to eliminating one of the six TIE Interceptors that were defending Polneye.
