Create a Save File
Start a new game by choosing one of the empty save slots. Use the Erase feature if all of the slots are in use. You can choose New Game to start from the beginning, or if you have completed Oracle of Seasons and received a Secret of Labrynna password you can choose Secrets to enter the password and begin a Linked Game of Oracle of Ages.
After choosing New Game, create a name for your character, then choose OK. You will be prompted to choose the message speed. You can change the message speed each time you play. After choosing it, the game begins.
After a cutscene, go north until you hear a cry for help. After another cutscene, go north. Then go to the left and walk close to the big rock with the triangle mark in it. Push the rock to the left.
Go north to the area that was blocked. Go north again to find some people and animals watching Nayru perform. Talk to all of the animals, then talk to the bear and it will move so you can sit and listen. Approach Nayru and there will be a cutscene.
Impa gives you the Wooden Sword (or, in a Linked Game, she gives you a shield; you already have a sword.) You can hold the button that it's assigned to to charge it and let go to do a spin attack.
Impa tells you to meet the Maku Tree in Lynna Village. Impa goes one screen east to Nayru's House.
Go to Lynna Village in the west, where you can meet the Maku Tree.
