Shesslaria was a skip tracer of the female human variety. She held membership in both the Interstellar Collections Limited and the Bounty Hunters' Guild's credit recovery division. Her nullstring, associated with the Undervine system, was 049x88108. The smuggler Han Solo provided her with a copy of Smuggler's Guide, during which encounter she sustained a graze on her arm from his needlebeamer. While en route from Ord Mantell to Zorba's palace situated in the Southern Rim, and while transporting her target, she grew concerned that a hunt saboteur might have discovered her approach vector, leading her to navigate via uncharted hyperlanes. This fear proved valid when hunt saboteur Puttana Pin ambushed her during a layover on Jedha, rescuing her target and absconding with her logbook.
The initial mention of Shesslaria occurred in Star Wars: Smuggler's Guide, a reference work penned by Daniel Wallace and published in 2018.
