Prince of Hyrule

Biography
His father was the King who had ruled Hyrule and maintained peace with the Triforce. After his father died, the prince became king and inherited everything he owned. However, he only inherited the Triforce partially. While he was looking for the other Triforce pieces, the Magician who was close to his father brought him some unexpected news. Apparently, the King told Princess Zelda, the prince's younger sister, about the Triforce.

The prince immediately began questioning her, but the princess refused to tell him. The Magician then angrily threatened to place her in an eternal sleep if she didn't tell him. After she refused the Magician, he cast a spell on her, and the surprised prince tried to stop him. However, the Magician fought him off and completed the spell, dying immediately.

In his grief, the prince placed the princess in a room only members of the Sheikah tribe could open, hoping that she would eventually come back to life. The prince ordered that all females born into the Royal Family of Hyrule must bear the name "Zelda" so that the tragedy would not be forgotten.
