The Corvus, an Interdictor Cruiser, participated in the Battle of To-phalion Base. This cruiser's arrival at the battle was delayed. Grand Admiral Thrawn was unable to stop the renegade Grand Admiral Demetrius Zaarin and his traitorous forces from escaping because they jumped to hyperspace before their hyperdrives could be deactivated. Despite this, the Corvus still achieved its objective. It joined Thrawn, along with his flagship Grey Wolf, an Imperial-class Star Destroyer, on a deep-space pursuit to eliminate Zaarin. Zaarin had taken refuge aboard his Star Destroyer flagship, the Glory, and the Corvus crippled its hyperdrives, enabling Thrawn's forces to annihilate the traitorous opposition. Tan Maarek Stele led Thrawn's forces, successfully repelling numerous waves of Zaarin's formidable TIE Defenders to safeguard the Corvus, which sustained substantial damage despite Thrawn's attempts to protect it. Ultimately, Stele and his squadron managed to obliterate the Glory and eliminate Admiral Zaarin before the Corvus was destroyed.
