Razka Karn is a Bajoran who appears in the fourth-season Deep Space Nine episode Indiscretion. He supplied the resistance during the Occupation and has since made a living salvaging and trading wreckage on the fringes of the Badlands, not always legally.
Knowing that Kira has long searched for news of Lorit Akrem, a friend who was a prisoner on the Ravinok, Razka sends word that he has come by a piece of metal that may be from the ship. Kira meets him, and analysis confirms it.
The lead sends her into the Dozaria system. The Cardassian government insists on sending a representative with her, who proves to be Dukat, in search of his daughter Tora Ziyal.
