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 fist appeared to Link when he had just ventured outside from the Temple of Droplets. Gustaf was one of the ancient Hylian kings. In Minish Cap, he directs Link to his grave and gives him a gold Kinstone to enter the land of the Wind Tribe.
