Gunder Vren was a male individual who served as an agent of the Rebel Alliance during the Galactic Civil War. After the slicing program the Shard of Alderaan was stolen from the Alliance by the criminal entrepreneur Begas Tok, Tok attempted to auction the program aboard the sail barge Dune Princess on the planet Tatooine. Vren attended the sale in an attempt to recover the program, but after a sandstorm erupted, Vren was trapped aboard the barge while several other Rebel agents waited for him in the city Mos Eisley.
