Volcano Summit

The Volcano Summit is a large volcanic cavern found deep inside and near the crater of Eldin Volcano in Skyward Sword. As described by Ledd the Mogma, it is too hot for a normal traveler to explore. Link must travel through the summit many times in a row to extinguish the various pillars of flames that are blocking the path to the Fire Sanctuary where Din's Sacred Flame rests.

Appearance and Features
The Volcano Summit is a super-heated area surrounded by flows of lava located deep inside Eldin Volcano. No human can traverse the landscape without protection; Link receives the Fireshield Earrings after completing Din's Silent Realm Trial; the earrings enable him to do just that. There is also a large outside area of the summit comprised of large, vine covered rock pillars and a small spring which Link may visit to fill up Empty Bottles.

The Volcano Summit leads to the entrance to the Fire Sanctuary which Gorko the Goron, who suspects that there are many Goddess Cubes nearby, states is blocked by pillars of flames. In order to extinguished them, Link must pour Bottled Water onto the tongues of the frog statues above them. Later Link has to lead the Ancient Robot Scrapper, who is carrying the Water Dragon's Basin, through the cavern, fending off the Lizalfos and other native enemies who have settled in the area. Eventually they extinguish the flames blocking the entrance to the Fire Sanctuary, allowing Link to continue to his adventure to find the final Sacred Flame.

Later, Link is captured and imprisoned by the local Bokoblins after Eldin Volcano erupts while he is descending into the area. He returns to the summit after escaping and reclaiming his equipment and blade from the demons to find a chamber inside the cavern that houses Eldin the Fire Dragon, who caused the eruption out of an explosion of his power. Link learns the second part of the Song of the Hero from him.

Trivia

 * The Volcano Summit and Death Mountain Crater seem to be very closely related or the same location due to many theorizing Eldin Volcano becomes Death Mountain in the future.
 * Both the Volcano Summit and Death Mountain Crater give damage to Link due to the extreme heat. The only way Link can prevent this is by recieving an item in this case the Goron Tunic and the Fireshield Earrings.
