Sacred Flame

The Sacred Flames are Key Items in The Legend of Zelda: Skyward Sword.

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 pass the three Silent Realm and prove himself by tempering the Goddess Sword with the Sacred Flames.

There are three sacred flames, one for each of the Golden Goddesses. 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 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 hides deep within the Fire Sanctuary. After obtaining each of the three sacred flames and traveling through the Gate of Time, Hylia herself grants the now-Master Sword a final blessing, transforming it into the True Master Sword and giving it the ability to smite evil.
