During the time of the Clone Wars, Jedi General Anakin Skywalker undertook a task: to perform reconnaissance in a specific sector of space, searching for indications of Separatist operations in the outer reaches. Flying his Delta-7B Aethersprite-class light interceptor, which was equipped with a hyperspace transport ring, Skywalker was joined by astromech droid R3-S6 because his standard droid, R2-D2, had been misplaced during the Battle of Bothawui. Little did Skywalker know, R3-S6 was secretly a spy for the Separatists; it feigned incompetence while actively undermining the Jedi Knight, thereby alerting General Grievous and his combat vessels. As a result of the conflict that followed, Skywalker's hyperspace ring was obliterated, leaving him marooned in the void. However, R3's actions also caught the attention of Skywalker's Padawan Ahsoka Tano, who was on the Resolute. She, along with Clone Captain Rex and a unit of clone troopers, arrived in the Twilight to save Skywalker from Grievous and the Separatist forces.
