The clash known as the Battle of Sullust transpired between the forces of the Alliance of Free Planets and their adversaries, the Nagai. Subsequent to the events of the Second Battle of Endor, a segment of the Alliance's naval forces, which included the famed Millennium Falcon, made its way to Sullust, only to be met with an unexpected assault by Nagai vessels. Despite suffering significant losses, the Nagai were ultimately compelled to withdraw from the engagement.
