Fyer

Fyer is an aging man who lives on the water of Lake Hylia in Twilight Princess. On his island, he offers strange cannon rides for a small fee; one shot out of Fyer's cannon has enough power to launch Link up to the bridge over the lake—an invaluable resource when Link has been changed back into human form with no way to warp to higher ground. Fyer, eventually, along with the badgering of Auru, an old friend of Fyer's, allows Link to experience the "Oasis Flight", which is a cannon ride that launches Link from the lake into the Gerudo Desert. Talking to Fyer after talking to Auru is the only way to further the quest to the Arbiter's Grounds, a sacred dungeon deep within the Gerudo territory.

Fyer also repairs the damaged Sky Cannon in order for Link to reach the City in the Sky. Although, he does charge a rather steep 300 Rupees for the job.

Trivia

 * Falbi and Fyer appear to be hovering over Lake Hylia with chickens, most likely from Flight by Fowl, in the end credits.
 * Fyer has an image of a Bullet Bill on his right (left in the Wii version) sleeve.
