In the interior of the castle, Link will finally meet Zelda, Princess of Hyrule. Although she appears to be a young girl, she is wise beyond her years, and has much useful information to tell. Listen carefully to everything she says. In addition to telling Hyrule’s legends, she will also give Link a letter that will function as a pass through restricted areas. Show this letter to anyone who blocks your path. Link will also get a glimpse of the scheming Ganondorf as he has an audience with the King of Hyrule. Vowing to unite with Zelda against Ganondorf’s plot, Link sets out from the castle to find the remaining two Spiritual Stones, starting with the Goron’s Ruby of Death Mountain. Before leaving the Castle, though, you’ll meet Zelda’s retainer and bodyguard, Impa. Impa will teach you a new song for your Ocarina. Zelda’s Lullaby is one of the most important and powerful tunes in the game! After meeting Impa, head northeast from the castle to reach Kakariko Village and Death Mountain.
