Nogo Sistek was a Corellian known for his knowledge of hiding places in the Greater Javin sector, as well as the beings hidden in them. For the right price, those seeking a deal with Sistek could buy his information and his promise to keep the deal confidential - for six months.

Sometime during the Galactic Civil War, he was approached by a man working for someone called Barseth Gynes who requested his services. The deal went sour after he located the infamous pirates Salmakk and Clabburn and provided them with millions of credits, allowing them to go back into business. Fearing for his life, Sistek went into hiding himself.
