Vinna Jiss, a Human female, served as a logistics staff member within the Grand Army of the Republic. During the Clone Wars, she betrayed the Republic and aligned herself with the Separatists, operating under the supervision of Besany Wennen.
During the year 21 BBY, Vinna engaged in a clandestine agreement with Paxaz Izhiq, a Falleen involved in criminal activities. Their plan involved the exchange of illicit items within a warehouse situated between two freighters. Unfortunately for her, clone commandos named Fi and Sev apprehended her, subjecting her to interrogation to extract crucial intelligence. Following her complete disclosure, Walon Vau carried out her execution. Subsequently, Jinart, a Gurlanin, adopted her likeness, unaware that the real Vinna Jiss had already met her demise at the hands of Vau.
