Luke has sensed the presence of Darth Vader growing closer. He helps to plan the defense of the Coway village against the impending Imperial attack. The attack, led by Vader and Grammel is repelled. As Vader retreats, Luke notices that the Dark Lord is heading in the direction of the Temple of Pomojema, which is said to hold the legendary Kaiburr Crystal. After beating Vader to the temple, Luke puts up a good fight against Vader eventually cutting off the Dark Lord's right arm. Vader calls his lightsaber to his left hand and it seems that Luke's fate is sealed until Vader trips over his severed arm falling into a dark pit. Having retrieved it from the statue of Pomojema, Halla gives Luke the Kaiburr Crystal and he uses it to heal himself and Leia. Luke, Leia, Halla, C-3PO and R2-D2 get into the crawler that they commandeered and leave the temple for a meeting on Circarpous IV.
