Krestrel D'Naran held the position of primary adversary to Jabba Desilijic Tiure. Sometime between approximately 8 BBY and 2 BBY, Jabba enlisted the services of Han Solo and Chewbacca, who were smugglers, along with Greedo, a bounty hunter. He tasked them with a journey to the planet Corellia with the goal of retrieving a verillix urn that they were informed contained the cremated remains of D'Naran. However, the urn actually held the neural core belonging to Ajax Sigma, a droid insurgent who had met his destruction at the hands of the Jedi Order many centuries prior.
