Steergard was the site of the one of the Galactic Empire's naval bases. Some of Steergard's Imperial technology was stolen by thieves that interacted with the rebel agent Luthen Rael and his shadowy anti-Imperial network. Dedra Meero, a Supervisor in the Empire's Imperial Security Bureau, had jurisdiction over Steergard's sector and began investigating a link with one of the thefts there and thefts of Imperial technology elsewhere.
During the time of the Galactic Empire, an Imperial Naval Base operated in Steergard, holding valuable Imperial technology. By 5 BBY, there were multiple thefts of Imperial technology from Steergard, one in which some of its were taken and eventually fell into the hands of Luthen Rael, the coordinator of a shadowy anti-Imperial network. Additionally the thief Cassian Andor infiltrated the naval base dressed in Imperial uniform and carrying a toolkit, stealing an Imperial N-S9 Starpath Unit sealed there without any bother. Andor attempted to sell the stolen tech to Rael, but the pair were interrupted when the Pre-Mor Authority Security Forces tried to apprehend the thief over a different crime.
The starpath unit was left at the scene and recovered by the Empire, with Supervisor Dedra Meero of the Empire's Imperial Security Bureau, who oversaw Steergard's sector as well as another. Meero was able to investigate the matter further under suspicions of the existence of Rael's network, trying to link it with thefts at locations like Kessel, Fondor, Jakku, and Base Cay. Later on, rebel pilot associated with the Neo-Separatist Anto Kreegyr was caught near Steergard and held on a destroyer where he was interrogated by Doctor Gorst.
Steergard was first mentioned in "Reckoning," the third episode of the first season of Tony Gilroy's live-action Disney+ series Andor, which aired on September 21, 2022. The scene where the location is mentioned was previewed in the clip "Steal from the Empire," which was released on August 24 of that year.
