Elemental Medallions

Ocarina of Time
The Elemental Medallions were representative of the Sages' power. After Link was awoken from seven years sleep by Rauru, Link had to collect these after freeing the Sages, in order to defeat Ganondorf. In the end, the medallions were used to seal Ganondorf into the Sacred Realm.

The Six Medalions are:
 * Light Medallion
 * Forest Medallion
 * Fire Medallion
 * Water Medallion
 * Shadow Medallion
 * Spirit Medallion

Additional Appearances
In The Legend of Zelda: Twilight Princess, the medallions appear at various places such as doors in dungeons. All six are on the columns of Mirror Chamber in the Arbiter's Grounds. The Water Medallion has been broken for an unknown reason, but this may be related to the destruction of one of the Sages by Ganondorf just before his banishment.
