*Kay Vess, also known by the alias Toren Valario Nupp, was a young human female thief from the Worker's District in Canto Bight on the planet Cantonica, who was raised and trained by her mother Riko Vess, becoming a scoundrel, pirate, and thief. After one too many jobs gone wrong, Vess ended up taking a job to rob the mansion of the crime lord Sliro Ruback of the Zerek Besh syndicate, but ended up captured by Zerek Besh after the rest of the crew revealed themselves to be members of the Rebel Alliance. Vess managed to escape and stole the EML-850 light freighter Trailblazer. After having the ship repaired, she was hired by the crime lord Jaylen Vrax to put together a crew pulling off a Heist once again on Sliro's mansion, with the BX-series droid commando ND-5 as her partner. She would eventually gather the crew in the Outer Rim, working towards a life free from Zerek Besh's death mark, and earning reputation in crime syndicates across the galaxy.
