In a faraway world, an event of cosmic importance is about to occur: a Great Conjunction of the planet's Three Suns. A thousand years ago, when the suns last came together, a cruel and selfish tribe known as the Skeksis seized control of the radiant Crystal that once brought harmony to all beings. A quarrel erupted and blows were struck, fracturing the Crystal and sending a shard flying off into the contryside. The Crystal darkened, and evil spread like a cloud across the land. Now, as Jen, the last known survivor of the Gelfling race, it is up to you to travel the world and fulfill an ancient prophency by restoring the missing shard of the Dark Crystal. The power to end the Skeksis' reign is yours. But there si much to be learned, and time is short. Unless you heal the Crystal before the Great Conjunction, all things whole and good will be destroyed, and the tyranny of the Skeksis will be reconfirmed forever!
