Selto Durka (played by David Wheeler) was a legendary Peacekeeper captain in command of the command carrier "Zelbinion". His most famed accomplishments were the liberation of Mintaka III and the quelling the Senovion rebellion. Many of his tactics are required learning during Peacekeeper training. Durka was also an inveterate sadist, and frequently tortured prisoners that came under his supervision. In Farscape, he was particularly known for torturing Rygel. He was first seen in PK Tech Girl, then in Durka Returns, and finally in Liars, Guns and Money.
