The Athega system was the home of the planet known as Nkllon. Due to the system's star being incredibly hot, access was restricted until Lando Calrissian, with the support of the New Republic, spearheaded an expedition to Nkllon for the purpose of extracting the abundant minerals present on its surface.
During the time of the Galactic Civil War, a space battle occurred within this system, pitting the Alliance to Restore the Republic against the forces of the Galactic Empire.
