The Dark Crystal is closely based on Jim Henson's film of the same name. The game is set in Thra, a world with three suns, which come together every thousand years in an event known as "The Great Conjunction". The player controls Jen, the last survivor of the Gelfings, a race of mole-like people. He must find a dark crystal and its broken shard, and repair it to end the reign of a tyrannical lord.
