The Royal Jewels are items in Four Swords Adventures. They are protected by each of the four Knights of Hyrule and come in four colors. The Royal Jewels are required to open a path to the Palace of Winds in the Realm of the Heavens. Upon taking over, Ganon turned all of the knights into Big Dark Stalfos and cursed each of the jewels to be portals to the Dark World.
Four Swords Adventures
Blue Royal Jewel
The Blue Royal Jewel is guarded by the Blue Knight and located within The Field. The knight has turned into a Big Dark Stalfos that the Links must defeat. When they do, the Blue Knight apologizes for attacking them and grants them the Blue Jewel.
Green Royal Jewel
The Green Royal Jewel is located at Kakariko Village. Just as before, the heroes must defeat the Big Dark Stalfos and free the Green Knight of Hyrule. The knight then reveals that the one who trapped him was not Vaati but someone else. However, he cannot remember who.
Red Royal Jewel
The Red Royal Jewel is within the Desert of Doubt. Once the Red Knight's cursed form is defeated, the knight reiterates that Vaati was not the one who cursed them, but rather someone from the desert. He then grants them the royal jewel.
Purple Royal Jewel
- ↑ "Blue Royal Jewel (Critical)
A jewel guarded by the Blue Knight, one of the Knights of Hyrule serving the royal family. Collecting this, along with the red, green, and purple jewels, opens the path to the Palace of Winds in the Realm of the Heavens." — pg. 117, The Legend of Zelda: Encyclopedia
- ↑ 2.1 2.2 "[sfx]I am the Knight of Hyrule charged with guarding the blue royal jewel. To my shame, I fell under the sway of dark powers and was transformed into a base creature of magic. The jewel was also cursed, and it became a portal to the Dark World. I am sorry for the citizens of Hyrule who suffered... and for Princess Zelda! I trust that you are going to the Realm of the Heavens and the Palace of Winds. However, you must first gather the royal jewels to reveal the path to the Tower of Winds. There are three other guardian knights. I fear they too have been changed. Free them from their dark curses and retrieve the jewels! The light must return to Hyrule! I entrust you with the blue royal jewel. And with it, I place in your hands the hopes of all Hyrule!" — Blue Knight, Four Swords Adventures.
- ↑ "[sfx]Bearer of the Four Sword. I am the Knight of Hyrule charged with guarding the green royal jewel. The Four Sword was the seal to Vaati's prison. If you have it, that means the seal has been broken. Yet the one who enshrouded me in darkness was not Vaati! It was... Ah! If the one who enchanted me and turned the jewel into a dark portal wanted Vaati restored... His goal must be to use Vaati to remake Hyrule into a land of darkness. Listen to me, heroes. You must never forget that Vaati is not the only foe you face. I will follow my brother knight's lead and entrust to you this green royal jewel. Now go! You and the Four Sword!" — Green Knight, Four Swords Adventures.
- ↑ "[sfx]I am the Knight of Hyrule charged with guarding the red royal jewel. Hear now the doom of the knights. We were bested by a foe with a mighty weapon. He cast us into the Dark World, where we and the jewels were lost in shadow. The Tower of Winds vanished, and I... No, WE servants of the crown were turned into monsters! The man that defeated us is also the same man who created that shadowy imp. A man from the desert wastes... He is not Vaati. Your dark twin was sent by him to trick you into breaking Vaati's seal. I wonder where the fiend got the amazing power he now wields. It matters not! None of this allows me to aid Princess Zelda. And yet I cannot go on... Brave ones...I entrust the red royal jewel to you. You now possess three of them. Obtain the fourth, and bring light back to the Realm of the Heavens!" — Red Knight, Four Swords Adventures.
- ↑ "[sfx]Heroes! You've done well to get this far... I am the Knight of Hyrule charged with guarding the purple royal jewel. Thanks to you, we have been freed from the dark spells that bound us. You must now take the four royal jewels past this ice-bound temple and fly to sacred grounds! Then you can enter the tower leading to the Palace of Winds, where Vaati lurks. Deep within the palace, which soars above the Realm of the Heavens, a terrible darkness awaits you all. Yet if you do not dispel that darkness, true peace will never return to Hyrule. The fate of Princess Zelda-- and all of Hyrule--rests in your hands!" — Purple Knight, Four Swords Adventures.
