The Founding of the Nation by Tetra
The event takes place between the events of Phantom Hourglass and Spirit Tracks. When Tetra and her group of pirates arrive in the land of the Spirits of Good, they meet up with Anjean, the Lokomo guardian of the Tower of Spirits.
After Anjean bestows Tetra with the Spirit Flute, Tetra creates the new kingdom of Hyrule. Over the next 100 years, the land is populated with descendants of the immigrant Hyruleans and a prosperous nation is flourishing.
