The Wind Tribe

From Zelda Wiki.org

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 favorite people of Gustaf^{[citation needed]}, an ancient king of Hyrule, and the builders of the Palace of Winds.

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. If you fail to save Gregal before journeying to Cloud Tops via Veil Falls, Gregal will have died and obtaining the Light Arrows will be impossible.

The people who built the Wind Ruins. They now live above the clouds, suspended by their own magic ability to control wind.
