The Great Calamity is an event from The Legend of Zelda: Breath of the Wild. This event serves as the main historical context of the game. It corresponds to the disaster caused by Calamity Ganon throughout Hyrule that occurred one hundred years ago before Link's awakening from his long sleep inside the Shrine of Resurrection. After he awakens and leaves the Shrine, Link discovers a ruined Hyrule, in which are several ruined locations such as the Temple of Time and Hyrule Castle, which is now controlled by Calamity Ganon.
