5-Triad, a security protocol droid designed with masculine programming, functioned as a jailer at a detention center situated in Lonisa City on the planet Valo during the High Republic Era. During the commencement of the Republic Fair, when Ty Yorrick, Mantessa Chekkat, and the Jedi Padawan Ram Jomaram found themselves incarcerated within the facility, 5-Triad was their assigned warden, dismissing Jomaram's claims about who he was.
