Legend of the Sleeping Princess

Long ago a great ruler of Hyrule maintained peace using the Triforce, but once he died the Prince took over but only inherited the Triforce in part. A magician told him that before dying, the king told the Prince's sister, Princess Zelda, something about the Triforce. The Prince and the magician inquired about this, but she would say nothing. Against the Prince's orders, the magician put Zelda into a sleep from which she was not supposed to awake. In his grief, the Prince ordered that all female children of the royal household were to be named Zelda.
