The Mandragonian Mob was a criminal organization, who Hondo Ohnaka believed to be the worst in the galaxy. During the Imperial Era, the Mandragonian Mob acquired a sample of the deadly thornsuckle plant, hiring the Kaminoan scientist Kolac Pru to clone it for them, so they could inject it into the atmospheres of planets and wipe out the populations. Mahjo Reeloo, a former assistant of Pru, heard of the deal, and paid Han Solo and Chewbacca to take her to the Undervaults of Gwongdeen so she could destroy the plant.
