Sully Stark was a female human and a dissenting member of a clandestine underground movement that dedicated itself to the secure relocation of surviving Jedi.
Following the rise of the Galactic Empire, Sully Stark became a member of the Path, an organization focused on the rescue and smuggling of Jedi who had survived Order 66. While Obi-Wan Kenobi was still in the process of recovering from his battle with Darth Vader, she and Wade Resselian were in the midst of a discussion about how to infiltrate the Inquisitorius fortress located on Nur, with the objective of rescuing Leia Organa. However, she confessed that she lacked familiarity with the fortress's internal layout. Upon Kenobi's emergence from the bacta tank, he suggested utilizing T-47 airspeeders, but Sully rejected this idea, pointing out that they were typically employed for hauling sewage and were not designed for combat. Sully expressed her concern that Kenobi was not physically prepared to participate in the rescue mission due to his ongoing recovery, but Kenobi remained insistent. Tala Durith ultimately permitted him to join them on the mission, leveraging her Imperial security clearance to gain access to the fortress.
Later, Sully piloted one of the two T-47 airspeeders dispatched to assist in clearing the platform, enabling Kenobi, Durith, and Organa to evacuate the fortress. She then witnessed the Third Sister destroy Wade's airspeeder, an event that deeply affected her.
The role of Sully Stark was played by Maya Erskine. Her first appearance was in "Part IV" of Obi-Wan Kenobi. The character's last name was revealed in the credits of "Part V."
