Venk was a human male who served in the Galactic Empire's naval branch as a captain. During the Galactic Civil War, Venk was stationed aboard Commander Dreed's Star Destroyer while the vessel hunted for Alderaanians who had survived the destruction of their homeworld, Alderaan. After Dreed died on the planet Skaradosh in 0 ABY during a prisoner exchange with Princess Leia Organa of the Rebel Alliance, Venk assumed command of the Destroyer and led it to the planet Espirion to try and destroy the Alderaanian fleet gathered there. With the aid of the Espirion Multi, a vessel sent by the Alderaanian-descended inhabitants of Espirion, the Alderaanians destroyed the Star Destroyer and killed Venk.
