What do you do after you get the first pendant in link to the past?

After obtaining the first pendant in "The Legend of Zelda: A Link to the Past," you should head to the eastern part of Hyrule to access the Desert of Mystery. There, you'll need to complete the next dungeon, the Desert Palace, to acquire the second pendant. Make sure to gather items and heart pieces along the way to strengthen Link for upcoming challenges. Once you defeat the boss in the Desert Palace, you'll receive the second pendant.
