Embrose

Embrose is a character from Spirit Tracks. He is a member of the Lokomo race and Guardian of the Fire Realm who resides in the Fire Sanctuary. Like the rest of the Lokomo people, Embrose possesses a sacred instrument, his being the timpani, which generates energy to power the Spirit Tracks when played with another sacred instrument.

In order to access the chamber of the sanctuary in which Embrose is located, Link must first quell the fires that engulf the Goron Village by using some Mega Ice. Once done, he can speak to the Goron Elder, who will grant him to pass to the Fire Sanctuary located behind the village. Opening the Door of Friendship in the sanctuary yields to Embrose's chamber, who, upon meeting Link, introduces himself and mentions that he has heard of Link and Zelda's quest. Embrose then proceeds to teach Link a Lokomo Song that restores the Spirit Tracks leading to the Fire Temple after the young hero and the enthusiastic Lokomo perform the duet together using the Spirit Flute and the timpani, respectively. Before heading out to the temple, Embrose recommends to the young duo to talk to the Gorons to learn about the dangers of the mountain.

During the final battle against Malladus, Princess Zelda sings a duet with Link, and soon after this, all five of the Lokomos, including Embrose, join in to form a full orchestrated version of the piece. This melody weakens Malladus and reveals a weak spot in his back, which is necessary to defeat the Demon King once and for all.

Embrose is last seen during the ending credits when Anjean, along with the rest of the Lokomos, departs towards the heavens after the defeat of the Demon King since their protection is no longer needed in the land of Hyrule.

Trivia

 * It is likely that Embrose is a pun from "Embers", the traces of fire. The coals burning in the train let off embers.
 * Alternatively, however unlikely, it is also phonetically similar to M. Bros., another one of the many Super Mario Bros. references that Nintendo subtly fits into the majority of its games, in homage to its beginnings. Coincidentally, the element most commonly associated with Mario himself is the same as the realm in which Embrose resides, Fire.
 * Embrose's timpani looks somewhat like the Goron Drums from Majora's Mask.
