In the era of the Galactic Civil War, Grand Admiral Demetrius Zaarin received deliveries of advanced hyperdrive tech via a pair of Stimner class Cargo ferries. As part of a pre-arranged agreement during the Conflict at Mylok IV, Stimner ferries from Habeen made a connection with Zaarin's Nebulon-B2 frigate, the Shamus. This allowed Admiral Zaarin to analyze prototype hyperdrive models designed for use in the TIE Avenger. Despite enduring significant attacks from Nharwaak rebels while transferring the goods, Stimner 1 & 2 successfully delivered their entire payload to Imperial forces without damage.
