Ocarina of Time

During the events of a massive conflict known as the Hyrulean Civil War, a woman escaped the ravages of war with her child. The woman was gravely injured, but managed to reach Kokiri Forest, a sanctuary that deters all outsiders. Before passing away, she left the child in the care of the Great Deku Tree. The boy was to be raised as Kokiri, and would remain unaware of his destiny, until one day, when the Gerudo King of Thieves appeared in the forest and demanded Spiritual Stone from the Great Deku Tree. The mighty guardian tree refused to give it to him, sensing his evil intentions, and in return had a death curse put on him.
The Great Deku Tree entreats Navi, a young fairy of Kokiri Forest, to take the boy, known as Link, to the Great Deku Tree. After obtaining sword and shield, he approaches the Deku Tree. The tree tells Link of the curse on him, and the brave youth enters the Deku Tree to break the evil curse. Link successfully defeats the enemies inside, but the Deku Tree reveals that it was already too late for him even before he entered. In his last moments of life, he tells Link of the creation of Hyrule and the Triforce that Ganondorf desires. He reveals that it is Link's destiny to thwart the great evil and restore peace to Hyrule, and gives him the Spiritual Stone of the Forest, one of the three keys to unlocking the gates to the Sacred Realm, where the Triforce is kept. He is to seek out Zelda, the Princess of Hyrule. The Great Deku Tree, his purpose now fulfilled, withers and dies.
