Once inside the castle, Zelda will lead you to the courtyard where the Picori Festival ceremony is taking place. Here, the winner of the sword-fighting tournament, Vaati, will break the seal on the chest containing the Picori Blade. This event is a pivotal moment, as Vaati's actions unleash evil upon Hyrule and transform Princess Zelda into stone.
After Vaati's dramatic reveal and the subsequent chaos, you will be knocked unconscious. When you awaken, the King will instruct you to seek the help of the Minish (Picori) to restore the Picori Blade and save Zelda. This marks the true beginning of your quest. You'll be given the task of finding the Minish, a tiny race of beings who hold the key to defeating Vaati. Prepare for a journey that will take you across Hyrule and into the world of the very small.
