Urbosa, chief of the desert-dwelling Gerudo—assembled to pilot the Divine Beasts (Vah Ruta, Vah Medoh, Vah Rudania, and Vah Naboris, respectively) while Zelda and Link would face Ganon directly. However, on Zelda's seventeenth birthday, Ganon possessed the Guardians and Divine Beasts, turning them against Hyrule. King Rhoam and the Champions were killed, much of the kingdom was laid to waste, and Link was gravely wounded protecting Zelda while on their way to Fort Hateno. Zelda had Link taken to safety for him to heal, hid the Master Sword in Korok Forest under the protection of the Great Deku Tree, and used her light magic to seal herself and Ganon in Hyrule Castle. This cataclysmic tragedy came to be known over time as the Great Calamity. A century after being placed in a healing chamber in the Shrine of Resurrection, an amnesiac Link awakens in a now-ravaged Hyrule. He meets an old man, who eventually reveals himself as the lingering spirit of King Rhoam. Rhoam explains that Ganon, sealed in Hyrule Castle, has grown stronger; he pleads for Link to defeat Ganon before he regains his full strength, breaks free, and destroys the world.

The Divine Beasts weaken him, and after Link defeats him, he transforms into Dark Beast Ganon in an attempt to destroy the world. Zelda gives Link the Bow of Light, which allows him to weaken Ganon enough for Zelda to seal him away, restoring peace and allowing the spirits of King Rhoam and the Champions to depart to the afterlife. Sensing their presence, Link and Zelda smile fondly. If players have found all thirteen memories in the "Captured Memories" main quest, they unlock a post-credits cutscene in which Zelda declares that Hyrule must be rebuilt and that she and Link must begin the process by themselves. As Link and Zelda survey Hyrule and embark to restore it to—and perhaps beyond—its former glory, the princess confides in him that although her powers may have
