Temple of Light

The Light Temple is a sacred palace in the center of the Sacred Realm. The Seven Sages reside in the Chamber of the Sages inside of the temple. The Light Temple is accessed through the Temple of Time and the Pedestal of Time. The Master Sword, residing in the pedestal, is the key to the Sacred Realm. When it is drawn from the pedestal, a portal opens into the Light Temple.

When the Hero of Time drew the sacred blade from the pedestal, Ganondorf, the Gerudo thief king, walked into the portal, gaining access to the Realm, and hauling the Triforce. Upon taking the Triforce, in the moment known as the Great Cataclysm, the Sacred Realm was transformed into the Dark World. The Hero's spirit was sealed away in time for seven years inside the Temple following the Cataclysm.

In the seven long years that the Hero's spirit was trapped in time, Ganondorf and his army of Dark World monsters seized the Sacred Realm; the Temple being the only stronghold left. Rauru, the Sage of Light, last remaining sage, eventually awakened the Hero's spirit, now an adult, and ready to be the true Hero. He granted Link the Medallion of Light. The Hero set out into Hyrule, now under control by Ganondorf, to awaken five other sages: Saria, Darunia, Ruto, Impa, and Nabooru and add their power to the Light Temple. In a final battle with Ganondorf, Princess Zelda of the Royal Family reveals herself as the final sage, the Sage of Time.

Now with the seven sages awakened, their power formed a giant portal inside the Light Temple, which engulfed Ganondorf, now morphed into Ganon, and sealed him away inside the Dark World.

The Pyramid of Power in A Link to the Past may be the Light Temple after being morphed into the Dark World, because it is in the center of the Dark World where the Temple should be.
