The Dark Crystal (1982)

A thousand years ago on the planet Thra, two new races appeared when a Shard was shattered from the Crystal of Truth: the cruel Skeksis, who use continued corruption of the Crystal to extend their lives, and the gentle urRu, more commonly known as Mystics, who make their home in the Valley of Stones to await their destiny. The leader of the Mystics, the Master UrSu, raises a young Gelfling named Jen whose clan were slaughtered by the Skeksis. As the Great Conjunction of Thra’s three suns draws near, a dying UrSu instructs Jen to fulfil a prophecy to heal the Crystal by first retrieving the Shard from Aughra. If Jen fails to complete his quest before the three suns meet, the Skeksis will rule forever. As UrSu passes, the Skeksis’ Emperor, skekSo, also dies, leaving the position for the leader vacant. The Chamberlain, skekSil, and the Garthim Master, skekUng, challenge each other in a “Trial by Stone” for succession, resulting in skekUng defeating skekSil. SkekSil is stripped of his robes and banished, while skekUng is proclaimed the new emperor. When the Skeksis learn of Jen’s existence, they send their army of giant crab-like Garthim to capture him, with the cunning skekSil following.

Jen meets Aughra and enters her orrery, which she uses to predict the heavens, and she explains about the Conjunction before having Jen select the correct Shard. Before Aughra can explain Jen’s mission, the Garthim arrive and destroy the orrery, taking Aughra prisoner as Jen flees. Hearing the call of the Crystal, the Mystics leave their valley to return to the Castle of the Crystal. On his journey through a forest swamp, Jen meets Kira, another surviving Gelfling. The two learn more about each other when they accidentally “dreamfast”, sharing each other’s memories. They stay for a night with the Podlings who raised Kira, only for them and Kira’s pet Fizzgig to flee when the Garthim raid the village. They are nearly caught, but skekSil intervenes, keeping the Garthim from pursuing them. Jen and Kira discover a ruined Gelfling civilization with ancient writing describing the prophecy: “When single shines the triple sun, what was sundered and undone shall be whole, the two made one by Gelfling hand or else by none.” They are interrupted by skekSil, who reveals the prophecy was the reason for the Gelfling genocide while trying to trick them into coming with him to the castle.
