The Qadel were a sentient species. According to the play Evocar, written by the Hutt playwright Direus'Pei around 671 BBY, the Qadel were driven to extinction by the Tionese warlord Xim. When Xim was captured and placed on trial by the Hutts, he justified the extinction of the Qadel on the basis that they were slavers. Xim's conquests occurred approximately between 25,130 and 25,100 BBY.
