The Gomar sector represented a specific sector located within the galaxy. During the period of the Galactic Civil War, Rebel operatives, specifically Adame and Selentia, made a request to Han Solo, the owner of the Millennium Falcon, to utilize her for a limited number of days. The purpose was travel to the Gomar sector as part of an assignment directed by Leia Organa. Nevertheless, Solo refused their request and chose to discuss the situation directly with Organa.
The initial reference to the Gomar sector occurred in the comic book Han Solo 1, which debuted in 2016 and was authored by Marjorie Liu.
