The Blood Velkers were a gang active on Genarius, on the floating cities of Tolea Biqua and Varna Biqua. As with most gangs of young toughs, they spent their time amusing themselves and causing trouble. As a right of initiation, the Blood Velkers would race through the tunnels of Eskaron.
The Blood Velkers were first mentioned in the Living Force Campaign Guide. They were later called the "Blood Velkurs" in two supplementary articles. The spelling "Velker" is preferred as it is the earlier spelling and corresponds to the Velkers of Bespin, a flying creature.
