Yorseg, a low-level crime lord, ran his operations from a base located on the moon orbiting the planet Carz. After contracting the Smoking Blaster freighter crew to transport a consignment of security droid logic matrixes to Nilya Fek'ra, he betrayed them by dispatching pirates to seize the merchandise.
In the "Tales of the Smoking Blaster" adventure, the name "Yosger" is used at various points when referring to Yorseg.
