To the Kingdom of Hyrule Main Quest

In-game Description

At the Temple of Time, you saw the Master Sword vanish into a mysterious light. A white dragon then rose into the sky, parting the sea of clouds. You’re sure you heard Princess !Zelda say, “Link, you must find me.” Head to the land below to look for clues to her whereabouts. There’s no faster way to do that than to dive bravely from the sky island.
