Harridan, a vessel of the Victory-class Star Destroyer, served within the Imperial Starfleet throughout the duration of the Galactic Civil War.
During 4 ABY, the Harridan operated as part of Black Sword Command, acting as the primary defense ship for the N'zoth system. Its duties included safeguarding Black-15 and maintaining control over the indigenous Yevetha population. Approximately seven months following the Battle of Endor, the Harridan was redeployed from N'zoth to participate in a rearguard engagement at Notak.
Subsequently, after a period of three weeks, the Yevetha, under the leadership of Nil Spaar, successfully captured the Imperial warships and shipyards stationed at N'zoth. They proceeded to either massacre or enslave both the stationed troops and the civilian inhabitants of the system.
Within the narrative of Tyrant's Test, an Imperial vessel referred to as Harramin is identified as one of the ships that came under the control of the Yevetha. Certain interpretations suggest that this mention of Harramin is actually a typographical error for Harridan. This interpretation further implies that the Harridan returned to N'zoth, where it was subsequently seized by the Yevetha. Nevertheless, there appears to be a lack of supporting canon evidence for this specific sequence of events.
