The Harrower-class dreadnought that served as the flagship for Dark Council representative Darth Vengean was in service until his demise. Moff Masken captained this vessel in 3642 BBY, when it clashed with a Republic cruiser above Quesh, under the command of Admiral Monk. Unbeknownst to Vengean, Monk was a spy working for Darth Baras, Vengean's apprentice, who dispatched his own apprentice to assassinate Monk. This apprentice infiltrated the dreadnought in an attempt to locate Monk, only to discover from Masken that Monk and his forces had already abandoned ship, descending to the planet's surface.
