Once upon a time, wizards tried to conquer the Sacred Realm of Hyrule. The Spirits of Light sealed the wizards' power within the Shadow Crystal and banished them to the Twilight Realm beyond the Mirror of Twilight. Now, an evil menace is trying to find Midna, Princess of the Twilight Realm, and the fragments of the Shadow Crystal to gain the power to rule over both the Twilight Realm and the World of Light.

Link awakens in the Twilight Realm, in the form of a wolf! Here he meets Midna, and she escorts Link to Hyrule Castle where none other than Princess Zelda bestows a question upon him--if the world is to be saved from the encroaching darkness, Link must recover the shards of the Shadow Crystal. The task will be long and difficult, and Link will need to use new powers he doesn't know he has!
