After waking up, your first task is to head to Hyrule Castle. Exit your house and proceed north through Hyrule Town. Zelda will be waiting for you at the town entrance. Speak with her, and she will lead you to the castle. Follow her through the town square, past the various stalls and citizens enjoying the festival. This initial walk-through introduces you to the layout of Hyrule Town and its vibrant atmosphere.
Once you reach the castle gates, Zelda will open them for you. Continue following her through the castle grounds until you reach the main entrance. Inside, she'll guide you to her room. This segment is largely linear, designed to introduce you to the main characters and the initial plot setup. Pay attention to the dialogue, as it sets the stage for the grand adventure ahead. Don't worry about exploring too much at this point; the game will open up significantly later.
