The Krayts were a group involved in criminal activities on Nar Shaddaa throughout the Cold War, which took place between the Galactic Republic and the reconstituted Sith Empire. On one occasion, they managed to get their hands on reports pertaining to the Empire's Imperial Intelligence from the officer named Keeling. They were preparing to sell this information to the highest bidder when an Imperial intervened, stopping the sale and retrieving the reports.
The Krayts are featured as adversaries in Star Wars: The Old Republic, specifically on Nar Shaddaa. The name of this gang originates from the Krayt dragon species found on Tatooine.
