The Ardent-class fast frigate known as the Intruder saw action in the Imperial Navy throughout the Second Imperial Civil War. In the year 138 ABY, Captain Vaclen Tor held command of this vessel, and it took part in the attack on the Hidden Temple located on Taivas, a Jedi stronghold. However, in that engagement, the Intruder met its end, succumbing to the combined might of the Galactic Alliance and the [Empire-in-exile]'s](/article/empire-in-exile) fleets.
