TK-8190, a human male stormtrooper under the Galactic Empire on Bracca, encountered Jedi Padawan Cal Kestis after the latter fell onto his moving train while evading capture from Inquisitors. Although Kestis tried to reason with TK-8190, the stormtrooper mistook him for a stowaway and eventually reported the incident, leading to his demise and that of his companion at the hands of the Jedi.
