Fire Sanctuary (Dungeon)

The Fire Sanctuary is the sixth dungeon featured in Skyward Sword. It is located in the extremely hot Volcano Summit of Eldin Volcano. Link ventures inside in order to find the third and final Sacred Flame so that he can temper his sword. The Fire Sanctuary houses Magmanos and the Mogma Mitts, and its boss is Ghirahim.

Entrance to the Sanctuary
The Fire Sanctuary is a large, castle-like structure situated across a bridge that is going over a large gorge. In order to protect the riches hidden inside the Sanctuary, three pillars of flames block Link's objective path to the dungeon. The frog statues hanging above the flames have to be given water from Link's bottles to extinguish the flames. However, this method of dousing the flames is only possible for the first two frog statues. The third frog statue is larger than the two before it, and requires a large quantity of water, more than an Empty Bottle can hold. Link travels to Lake Floria to request the use of the Water Dragon's Basin from Faron, the Water Dragon. Upon returning to the base of Eldin Volcano with Scrapper the Ancient Robot, who is carrying the basin, Link is required to travel all the way up to the Fire Sanctuary while protecting Scrapper from the large number of enemies inhabiting the Eldin Volcano region. Reaching the Fire Sanctuary will cause Scrapper to pour the water basin over the frog's tongue and thus clearing the entrance to the Fire Sanctuary.

Themes and Navigation
There are many lava flows similar to those found in the Earth Temple, which Link must cross by shooting down Water Fruit (ideally with the Slingshot, though the Beetle, Clawshots and arrows work as well) hanging over the lava flows, which harden the lava into a safe platform. Navigating the Sanctuary requires changing the currents of lava flows, either in strength or direction, so that Link can have the hardened lava platforms move along with the current. The Fire Sanctuary also introduces getting around the area by tunneling underground with the Mogma Mitts, which Link receives after helping one of the treasure hunting Mogmas, named Silva, who has been trapped while looking for treasure. In fact, each Mogma rescued or spoken to will reward Link when he frees him. The second imprisoned character will give him the dungeon's map, and the third one will give him a Piece of Heart. In all cases, the reward is given inside a chest.

The Fire Sanctuary is famous among Mogmas for its illusory puzzle, which calls upon the courage of adventurers, known as the "Legend of the Sleeping Statue." Hidden in the dungeon is a chest with an Empty Bottle; Link can reach it in a balcony accessible after solving some unconspicious optional puzzles. In regards of the local bestiary, darker variations of known enemies make their appearance, and can curse Link for limited periods of time upon contact with their dark fog.

Trivia

 * Hardening the lava pools using Water Fruit is a similar concept to tossing the water pots in The Wind Waker in Dragon Roost Cavern.
 * Fire Sanctuary is the dungeon with the highest number of mini-boss battles in the series, with four in total.
