THE DARK CRYSTAL reveals the coming-of-age of the last male Gelfling on the planet of Thra. From his quiet, dreamy existence in the secluded valley with the ponderous but cerebral urRu, Jen must suddenly depart on a Quest whose details are not fully explained to him. This gentle boy leaves his comfort zone in a desperate attempt to save his planet from another miillenium of destructive rule.

Jen's goal is to find a special crystal shard and reunite it with the mother crystal -- now dark with grief and anger at the senseless destruction. This crystal is coveted and guarded in the Dark Castle by the vicious race of Skeksis, who terrorize the planet with their bat spies and insect zombies. Our unlikely hero has only his flute and his wits to guide him, but several surprise friends offer help and advice along his dangerous odyssey--including the last girl Gelfling. Together they race against celestial time, as the Great Conjunction of the triple suns is imminent.
