King Gustaf

King Gustaf is a character in The Legend of Zelda: The Minish Cap who is a former king of Hyrule. He is dead now but can be found in the graveyard and gives Link a Golden Kinstone that is needed to get to the Palace of Winds.

Theory
Some believe Gustaf could possibly be the "Hero of Men" referred to in the story of the War of the Bound Chest due to his statement that he ruled Hyrule "countless ages ago" and seemed to be an influential and well-respected person even to such peoples as the Wind Tribe. This is in no way proven, but it remains a possibility given Gustaf's mysterious background and his particular appearance within the story of The Minish Cap over other former rulers of Hyrule. This theory is also compounded by the fact that it was Gustaf who possessed the key to getting to the Cloud Tops and thus to the Wind Element stored within the Palace of Winds.
