Trail refers to two Lambda-class T-4a shuttles that were utilized by the Rebel Alliance throughout the Galactic Civil War. These shuttles, working alongside the related group Guild and the transport group Goode, attempted a defense against an assault on their base, which was made up of four Class-C cargo containers Berm and Class-B cargo container Clip. The attack was carried out by Imperial forces, and they were commanded by the frigate [Compton]. During the conflict, all Rebel forces were eliminated. To instruct future pilots, including Maarek Stele, the battle was simulated within the Combat chamber.
