Wind Waker

Long ago, there existed a kingdom where a golden power lay hidden. One day, a man of great evil found this power and took it for himself, and with it at his command, he spread darkness across the kingdom. But then... just as all hope had died, a young boy clothed in green appeared as if from nowhere. Wielding a blade that repelled evil, he sealed the dark one away and gave the land light.

This boy, who traveled through time to save the land, was known as the Hero of Time. The boy's tale was passed down through generations until it became legend.
