Sacred Flame

The three Sacred Flames are sacred relics used to enhance the powers of the Goddess Sword in Skyward Sword.

Location and Uses
After Zelda is spirited through the Gate of Time at the Temple of Time and the Gate is destroyed, Link goes back to the Sealed Grounds and is told by the old woman there that there is a second Gate of Time that can be activated with a Skyward Strike. However, in order for his strike to open the gate, Link must first temper the Goddess Sword with the Sacred Flames, which he can only acquire after passing the respective Silent Realm trial for each one and collecting the necessary items. Each of the Sacred Flames are named for one of the Golden Goddesses. After obtaining each of the three Sacred Flames and traveling through the Gate of Time, Hylia herself grants the sword, now in the form of the Master Sword, a final blessing, transforming it into the True Master Sword and giving it the ability to smite evil.

Farore's Flame
Farore's Flame lies deep within the Ancient Cistern. It lengthens the Goddess Sword, giving it extended reach and twice the strength.

Nayru's Flame
Nayru's Flame is housed within the Sandship, which was once protected by Skipper before pirates stole it. It unlocks the dowsing abilities of the Goddess Sword, allowing Fi to search for Rupees, Treasures, Gratitude Crystals, and Goddess Cubes.

Din's Flame
Din's Flame hides deep within the Fire Sanctuary.
