The shipyard was located on an island just off the coast and connected by a pair of causeways to the mainland. Among other products, it produced RZ-1 A-wing interceptors.
However, Sayan remained a hotbed of Nationalist sentiment. Running street battles between Imperial forces and Nationalists were common. At some point, the Empire became so fed up with Sayan's resistance that it moved in artillery platforms and began leveling the city.
When Brenn Tantor, the Imperial general who had reconquered the planet earlier, returned as a Rebel, he captured the Government Center and freed Hamman Flatt, a leader of the Abridon Nationalists. Flatt offered the Rebel Alliance a shipment of A-wings if Tantor would free Sayan.
Tantor covertly eased a Hover Transport full of pilots, the TR-MB, and an armed escort through the city, using Scanner Jammers and the confusion of the city's battles for cover. He was able to capture the shipyard, which he then used as a base of operations to land reinforcements and eliminate all Imperial forces in the city. The A-wings were delivered to the Rebellion unharmed.
