The extensive array of cruisers and starships known as the Nagai expeditionary force served as a refuge for the Nagais following the Tofs' seizure of their planet, Nagi. Their initial sighting occurred over Kinooine, where they forged an alliance with the Galactic Empire. This partnership aimed to assist the Nagai in retaliating for their defeat at Endor, inflicted by the Alliance of Free Planets. Subsequently, the fleet participated in significant engagements such as the Second Battle of Endor, the Battle of Iskalon, and various other conflicts during the Nagai–Tof War.
