Wind Tribe

The Wind Tribe is a group of people who originally lived in the Fortress of Winds. They have now moved to the Cloud Tops. They were the favourite people of Gustaf, an ancient king of Hyrule.

Early on in Link's adventure, he can do a Kinstone Fusion to reach the Cloud Tops via a magic portal in south Hyrule Field. Once there, you see an old man, named Gregal, with a ghost swirling around him. Suck the ghost up with the Gust Jar, and he will be better. When you return later in the game, Gregal will give you Light Arrows.

Quote from The Legend of Zelda: The Minish Cap The Wind Tribe figurine: "The people who built the Wind Ruins. They now live above the clouds, suspended by their own magic ability to control wind."
