Defiance's Banner was a starship that served as the flagship of the Sy Myrthian ex-senator Toonbuck Toora's Confederacy of Independent Systems holdout forces in the aftermath of the Clone Wars. During the Sy Myrthian Insurrection in 19 BBY, the Galactic Empire sent a task force led by the Praetor-class Star Battlecruiser Battalion to hunt down Defiance's Banner.
