During the Clone Wars, the Quaestor was one of several Praetor-class battlecruisers that received additional armor and weaponry before leading strikes deep into Separatist space; the Quaestor was destroyed at Pammant when it suffered a hyperdrive mishap due to sabotage and crashed into the planet. This crash also fractured the planet. After the rise of the Galactic Empire, the Praetor-class battlecruiser Battalion hunted Separatist remnant forces, participated in the conflict known as the Sy Myrthian Insurrection and helped destroy a faction at Trasemene. While stationed in the Dalchon sector, the ship's commander, Adar Tallon, had grown disenfranchised with the Empire and defected from military service with a loyal crew. To cover their escape, Tallon arranged to have the Battalion be destroyed by his friend, the pirate captain Quist, in a mock rescue attempt of a freighter under attack by pirates.
The Praetor-class was eventually succeeded by the Praetor Mark II-class battlecruiser. During the Galactic Civil War, a derelict Praetor was cannibalized by Rebel forces and its reactors were installed on the frozen planet Hoth to power the facilities of Echo Base, including its defensive systems.
The Praetor-class battlecruiser was first mentioned in Inside the Worlds of Star Wars Trilogy. The 2012 reference guide The Essential Guide to Warfare retconned the Quaestor, from Star Wars: Revenge of the Sith Incredible Cross-Sections, and the Battalion, from the West End Games roleplaying adventure Tatooine Manhunt, as Praetor-class battlecruisers.
