Spiritual Stone





In Hyrule during the era of Ocarina of Time, in order to open the Door of Time which sealed away the Master Sword in the Temple of Time, one needed the three Spiritual Stones.

The three stones are:
 * The Kokiri's Emerald a.k.a. the Spiritual Stone of Forest, which was held by the Great Deku Tree;
 * The Goron's Ruby a.k.a. the Spiritual Stone of Fire, a treasure held by Darunia;
 * The Zora's Sapphire a.k.a. the Spiritual Stone of Water, which was held by Princess Ruto.

During his quest to unlock the Sacred Realm and steal the Triforce, Ganondorf, the evil king of thieves was refused the Spiritual Stones by each of their respective guardians. In response, he cursed them all with various blights using dark magic. In order to obtain the stones to prevent the Triforce from falling into Ganondorf's hands, Link was required to free the guardians from Ganon's malevolence.

Kokiri's Emerald
The Spiritual Stone of Forest/Kokiri's Emerald, is one of the three Spiritual Stones Link had to acquire in order to open the Door of Time during his adventures in Ocarina of Time. By relieving the Great Deku Tree of the evil which had infested it, Link proved his courage, leading to it entrusting Link with this stone and the fate of Hyrule.

Goron's Ruby
The Spiritual Stone of Fire/Goron's Ruby is one of the three Spiritual Stones that Link had to collect in Ocarina of Time. It is a dearly held treasure of the Gorons. When Link manages to defeat the evil creatures inside Dodongo's Cavern where the Gorons get their food, he is given this stone by Darunia, the leader of the Gorons.

Zora's Sapphire
The Zora's Sapphire is the Spiritual Stone of Water which was passed down to Link by Princess Ruto, after he had saved her from inside of the giant whale Lord Jabu Jabu. After Link had saved her, Ruto fell in love with Link and gave him this stone as a symbol of their engagement. The stone was given to Ruto by her mother who said to give it to the man she would marry, which explains such odd actions.

Trivia

 * The Zora's Sapphire is also known as the Zora's Engagement Ring. This is why Ruto gives Link the Zora's Sapphire: as an engagement ring.
