Sheikah

The Sheikah are a race of humans. They swore loyalty to the Hylians and fought battles for the Hylians during the Unifying War. Most of the Sheikahs died in battle, but a few survived.

One of the most famous Sheikahs is Impa, Zelda's caretaker and the sage of the Shadow Temple. Another is Sheik, a mysterious character that helps out Link on his journey in The Legend of Zelda: Ocarina of Time.

There are some rumours about Agahnim being a Sheikah.
