Duran Gorr existed during the Cold War period as a Mandalorian marauder; he was a male Human. He commanded a Mandalorian band that engaged in the theft of Republic-owned warheads. Ultimately, Republic military personnel arrived to reclaim the stolen warheads, resulting in the deaths of Duran Gorr and his entire company. Duran Gorr's appearance included gray Mandalorian armor accented by white symbols, in addition to osseous tattoo designs upon his face.
Duran Gorr is featured as the ultimate antagonist in the "Fallen Stars" Heroic mission on Taris, accessible to Republic players in the video game Star Wars: The Old Republic, which was released in 2011.
