Doors of Virtue

The Doors of Virtue, known individually as the Door of Power, Door of Wisdom, and Door of Courage, are three objects from The Legend of Zelda: Phantom Hourglass. Massive doors located in the Temple of the Ocean King, these doors are decorated with the marks of the Three Spirits, and each one requires the corresponding spirit to unlock it. As such, Link is prevented from travelling past a certain point into the temple until he rescues the next spirit.
