Sacred Grove

The Sacred Grove is a place from The Legend of Zelda: Twilight Princess.

Deep within the Faron Province, adjacent to the Forest Temple entrance, is the Sacred Grove, an ancient garden that not only holds strong ties to the Royal Family, but also protects the Master Sword from outsiders. Upon entering the Sacred Grove, Wolf Link must howl the Zelda's Lullaby at the Howling Stone to set off a chain of events, including a long, relentless Skull Kid chase. This Skull Kid will traverse the forest, expecting Link to find him, in a difficult game of hide-and-seek. After finding the Skull Kid three times, he will retreat into a new area, a new section of the forest that is surrounded by ruins. He summons his skeletal minions at Link in hopes of distracting him from his horn-blowing, which would eventually be used to attack the Skull Kid in the end. The longer this game progresses, the tougher it becomes to reach the Skull Kid in time for him to blow his horn, as more and more of his minions strive to stand in Link's way. After striking at the Skull Kid three more times, he vanishes.

The actual area where the Master Sword lies is in the ruins of the Temple of Time from Ocarina of Time. At the end of Ocarina of Time Link replaces the Master Sword into the Pedestal of Time. In Twilight Princess, the new Link takes it out once again.

Later in the game, Link must travel to the Sacred Grove in the past--the halls of the Temple of Time. From there, he may access the rest of the Light Temple.

As the grove within itself is not marked on the map of Faron (though it receives a label), it is entirely plausible that it is the northeastern area of the Lost Woods; not only is the background music Saria's Song, but Skull Kids exist there.

Guard Puzzle
Before entering the final forested area where the Master Sword is hidden, one last puzzle awaits. The two guards that oversee the old Door of Time have dislocated themselves and expect Wolf Link to place them in their respective positions again. There are 60 ways to solve the puzzle. Due to its vertical symmetry, half of these combinations simply swap left and right.
