Splinter of The Mind's Eye - Plot

Plot

Luke and Leia are traveling to Circarpous IV to persuade the Circarpousians to join the Rebel Alliance. A strange energy storm forces them to crash land on the swampy planet Mimban. Luke, after finding Leia, begins looking for a station that would allow them to get off the planet but instead find a town near which agents of the Empire have a secret energy mine. Forced to keep their identities secret, Luke admonishes Leia to follow his lead, and in a nearby bar where they take refuge, claims she is his servant girl. An old woman named Halla approaches them; while revealing little of her own background, she identifies Luke as one who is strong with the Force and shows him a splinter of what she claims to be the Kaiburr crystal, a glowing crystal that magnifies and focuses the Force. Halla strikes a deal with Luke and Leia that if they help her find it, she will help them get off the planet. They leave together.

Upon emerging, Leia retorts that Luke ought not to have struck her; the two squabble as some miners emerge from the bar. The miners claim that fighting in public is against Imperial law here, and they all get into a brawl. Imperial stormtroopers intervene and take Luke, Leia and the miners to the local jail. They are questioned by Captain-Supervisor Grammel. The miners are taken away while Grammel continues questioning Luke and Leia. Grammel discovers and confiscates the crystal shard, along with Luke's weapons. Luke and Leia are placed in the maximum security cell with two drunken but friendly Yuzzem--hairy aboriginal creatures resembling squat Sasquatch--called Hin and Kee, while Grammel reports the incident and the crystal shard to Governor Bin Essada, in charge of the group of star systems including Circarpous.

Halla, with Luke's help, uses the Force to help rescue Luke, Leia and the two Yuzzem; the two Yuzzem rampage through the jail barracks, while Luke and Leia escape, and the four meet Halla to find the Temple of Pomojema, which Halla believes to be the location of the Kaiburr crystal. They travel through the swampy wilds of Mimban, during which travel they encounter a wandrella, a huge worm-like creature. The wandrella pursues them, forcing them to leave the transport and splitting Luke and Leia apart from Halla, the droids and the Yuzzem.

Luke and Leia hide in a deep well, down which the wandrella falls, leaving the two trapped in the well as it destroys their escape path; Halla mentions from the lip of the well that there must be an escape route, and Luke and Leia go in search of it, though their travels involve floating across a lake on lily pads, and fending off creatures of the deep with Luke's light saber. On the other side of the lake, they encounter the secretive residents of the caves, Coway guards/patrols. They kill all but one of the Coway; the survivor escapes and tells his Coway tribe about the visitors. Luke and Leia follow the single Coway to the tribe, where they find Halla's group being held as prisoners. To save his friends, Luke defeats the Coway's champion fighter. The Coway become his friends, but Luke senses Darth Vader. Coway patrols confirm Luke's feeling: Imperials, led by Darth Vader and Captain-Supervisor Grammel, are attacking the underground cave.

When the Imperials arrive, they are surprised by the Coway tribe's powerful response and face a debacle. Vader and Grammel retreat with the handful of surviving stormtroopers, though Vader loses patience with Grammel for the defeat and kills him. Luke and company steal an Imperial transport left behind, and begin travelling to the Temple themselves. They beat Vader to the temple and find the Kaiburr crystal. They encounter a monster, and unsuccessfully try to fight it off with blasters. Luke tells Hin and Kee to get some rifles. Luke cuts down one of the pillars holding up the temple, crushing the monsters. Luke's leg is pinned under a fallen boulder. Darth Vader then enters the Temple of Pomojema, announcing that he killed Hin and Kee. Leia takes up Luke's lightsaber and begins fighting Darth Vader, but he toys with her, giving her multiple superficial burns with his own saber. Hin, mortally wounded, shows up and in his dying act, lifts the big rock off of Luke's leg. Luke fights Vader, showing more skill than expected, deflecting some Force-based attacks and eventually slicing off Vader's arm. Despite this, the Sith Lord seems about to win, but then falls into a pit. Luke senses that Vader is still alive. As the story ends, Leia and Luke, healed by the crystal, drive off with Halla into the mists of Mimban.
