Sand Sanctuary

The Sand Sanctuary is a location within the Sand Realm of the re-established kingdom of Hyrule in. It is located in the sandy dunes just north of the waters of the Ocean Realm and is the home dwelling of the realm's Lokomo guardian, Rael.

Story
After defeating Byrne atop the Tower of Spirits and witnessing the revival of the Demon King Malladus, Link and Princess Zelda are sent by Anjean to recover the legendary Bow of Light from the final temple in the kingdom of Hyrule far across the dunes of the Sand Realm, the Sand Temple. To reach the temple across the desert sands, Link sees that like all the other realms he has visited, he must first restore the realm's lost Spirit Tracks that lead to the temple in order to fully explore it. After succeeding in restoring enough of the tracks through the use of a Force Gem given to them by Anjean to reach the Sand Sanctuary, the pair travel to the Sand Realm to restore the final temple and recover the only weapon capable of banishing Malladus from a human host.

Link at first finds the area of the sanctuary to be an empty clearing of sand, but soon realizes the area is a miniature model of the entire desert. After reading an ancient inscription nearby, the young hero must journey around the Sand Realm to find the four giant head statues scattered around the realm and trace their gazes to find their intersection. Once done so, the place where the gazes intersect on the map is the same place where Link must place a bomb in the sanctuary, where it will reveal the hidden doorway to the sanctuary's inner sanctums as well as Rael, the Lokomo sage. Together, he and Link perform the necessary Lokomo Song with Link wielding the Spirit Flute, restoring the Spirit Tracks and reopening the path to the Sand Temple far across the desert.

Force Gem
After Link completes the Sand Temple, Link can bring Rael five Cuccos from Hyrule Castle Town to help him with his Cucco research, which consists of harnessing the unbelievable power the Cuccos possess when they call others as they are being threatened by others and use this power for the good of mankind. As a sign of gratitude, Rael will give the young hero a Force Gem that reveals more tracks in the Fire Realm, opening way to the Ends of the Earth Station.
