Gabrial Atanna was a male from the planet Esseles in the Core Worlds. He served as Esseles' senator in the senates of both the Galactic Republic and its successor state, the Galactic Empire, until Emperor Palpatine dissolved the body in 0 BBY. Retiring to his estate in the city of Calamar on his homeworld with his wife, Atanna spied on Esseles' defense industries for the Alliance to Restore the Republic. After Atanna was compromised and arrested by the Empire, Alliance teams were dispatched to rescue him as well as his wife and grandchildren.
