In 2 ABY, Imperial walkers from the Vanguard paraded on Coruscant at the overture of the New Year Fete Week festivities.
The Star Destroyer was best known for being the flagship of then-Vice Admiral Thrawn during Grand Admiral Demetrius Zaarin's attempted coup approximately one year before the Battle of Endor.
After Zaarin managed to take Emperor Palpatine prisoner from aboard the Star Destroyer Majestic, Zaarin had Palpatine transferred to a Delta-class JV-7 escort shuttle which was tasked with rendezvousing with Zaarin's flagship, Glory.
Hoping to stop the exchange and rescue the Emperor, Lord Darth Vader, along with ace pilot Maarek Stele, deployed from aboard the Vanguard in a TIE/sa bomber assault on the Glory. Taken by surprise, Zaarin was forced to withdraw, and the Vanguard successfully rescued Palpatine.
While in the game Star Wars: TIE Fighter Vanguard is an Imperial I-class Star Destroyer, it is erroneously classified as a Victory I-class Star Destroyer in TIE Fighter Collector's CD-ROM: The Official Strategy Guide.
