Petor was a CR90 corvette that the Nharwaak forces used to protect their base of operations at the Mylok IV Conflict during the Galactic Civil War. Imperial Grand Admiral Zaarin's forces destroyed Petor from Imperial Nebulon-B2 frigate Shamus on the Nharwaak base workshop, as a retalitory strike for interfering with the Habeen arrangement to sell new hyperdrive technology to the Empire.
