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 and Midna head for Snowpeak to find the pieces of the Mirror of Shadow which they will need to defeat the evil Ganondorf. Link has fought and defeated many terrible foes in his quest to save Hyrule and the Twilight Realm, but Midna now begins to worry that all that Link has seen and his obsession with power are changing him. What will Link do if his greatest enemy turns out to be...himself?
