The Justice, a Harrower-class dreadnought, served the reestablished Sith Empire during the era known as the Cold War.
Commander Harron Tavus, previously an officer within the Republic Army's Special Forces Division and leader of Havoc Squad, commanded the Justice as his flagship. The Empire granted him the vessel following his and hundreds of other SpecFor personnel's defection in 3643 BBY, a consequence of their growing discontent with the Galactic Republic. Tavus himself named the ship, perhaps hinting at the reasons behind his betrayal. Given that Harrower-class dreadnoughts formed the core of the Imperial Armada, entrusting such a warship to a Republic defector indicated the Empire's profound trust in Tavus.
After the Lieutenant, who had assumed command of a reformed Havoc Squad, began systematically hunting down and eliminating the defectors and their resources across planets like Taris, Nar Shaddaa, Tatooine, and Alderaan, Tavus summoned his remaining loyalists to the Justice. However, Special Forces intercepted all of his communications. General Elin Garza, the commanding officer of the Special Forces Division, dispatched Havoc Squad to the Justice under the pretense of answering Tavus's call. Their true objective was to first disable the ship's hyperdrive, and then proceed to the bridge to neutralize Tavus.
Following the disabling of the hyperdrive and the defeat of Wraith, the last of the Havoc traitors under Tavus's command, Havoc Squad advanced to the bridge and defeated Tavus. Subsequently, General Garza boarded the vessel with her guard troopers to seize control of the ship.
