Gustaf

Quote from The Legend of Zelda: The Minish Cap Gustaf, Royal Spirit figurine:

"The spirit of an ancient king of Hyrule who wishes to secure peace in his land from beyond the grave. He was very fond of the people of the Wind Tribe."

Gustaf was one of the ancient Hylian kings. In Minish Cap, he directs you to his grave and gives you a gold Kinstone to enter the land of the Wind Tribe.

In the beggining of the game it tells of a "hero of men" and which Gustaf was. He was later dubbed King of Hyrule for ending the war.
