The Nagai expeditionary force was a large collection of cruisers and starships. It was first seen above Kinooine. The forces aboard the ships were composed of both Nagai and Imperial personnel, for the Empire aided the Nagai to avenge their defeat at Endor at the hands of the Alliance of Free Planets. The fleet later fought in the Second Battle of Endor, the Battle of Iskalon, and other battles throughout the Nagai–Tof War.
