Jessa Vandangante was a Human female. She was the offspring of Klaus "Doc" Vandangante and Shardra, who jointly headed a band of outlaw techs that operated within the vicinity of the Corporate Sector.
Shardra, Jessa's mother, passed away during Jessa's early years. Consequently, Doc raised Jessa. Jessa acquired leadership qualities from her deceased mother as well as her paternal grandmother, Carmilla Vandangante, Doc's mother. Before long, Jessa became the second-in-command of the outlaw techs, taking charge of the group whenever Doc was absent, either negotiating deals or scouting potential new bases.
Following her father's disappearance, Jessa assumed the leadership position. She maintained the group's cohesion, disregarding fearful proposals to abandon their established infrastructure. Jessa, believing her father had been seized by the Corporate Sector Authority, struck an agreement with Han Solo and Chewbacca to assist Rekkon, a scholar residing on Orron III, in the search for several political prisoners who had vanished within the Sector. Solo not only discovered the Authority's clandestine Stars' End penal facility, but he also obliterated it, liberating Doc and the other captives. Subsequently, Doc, Jessa, and their outlaw techs moved their operations to Urdur. She and Han shared a short romance prior to Han's return to his life as a smuggler.
