The Gorm Space Navy (GSN) Superdreadnought is an original design by Todd Dillen, based on Jack Southerland's Starfire artwork on the back cover of the 3rd Edition Rulebook.
The Empire of Gormus was a spacefaring race that encountered the Khanate of Orion between ISW-2 and ISW-3. After a string of defeats fighting the Terran Federation, the Khanate of Orion craftily defeated the Gorm Space Navy. The Khanate of Orion were so impressed by the Gorm's prowess and honor in combat that they offered an immediate partnership to the Khanate. The offer was accepted.
