Quelev Tapper was a Human male smuggler who operated during the Galactic Civil War. Formerly the head of his own organization, Tapper agreed to merge with fellow smuggler Talon Karrde's smuggling group after Imperial forces leveled his headquarters and destroyed three quarters of his operation. Tapper became Karrde's second-in-command and most trusted lieutenant, and his conservative personality countered Karrde's more flamboyant nature. The pair would often personally investigate new business opportunities.
