Klag was a male Klingon who operated as a smuggler in the 2370s.
In 2371, Klag was working on a scheme with Quark in which he would take his ship into the Gamma Quadrant under the auspices of conducting tours, while in reality, Klag was meeting with other smugglers. Klag's starship was docked at Deep Space 9 when the station was threatened with destruction by asteroids and was used by Miles O'Brien to destroy the largest of the asteroids.
