Sacred Realm

The Sacred Realm is where the Triforce was once kept. The ancient Hylians prevented access to the Sacred Realm and the treasure held within it by sealing the gateway with the Door of Time, three Spiritual Stones, and the Master Sword. When Ganondorf inadvertantly gained entry to the Realm in Ocarina of Time, he seized the Triforce and turned the Sacred Realm into the Evil Realm.
