Head to the western side of the room, first, and save the game. Then go up the northern staircase and speak with the woman sitting nearby. You’ll be told to go to the Faron Woods to the east of here.
You’ll also learn how to place beacons and about beacons in general. When allowed, place a beacon on the X on the map. Exit the map and continue speaking with the woman. Afterwards, go to the lower area, in the northeastern corner, and open the chest to not only receive a Bottle , but one filled with some Revitalizing Potion ! Use the Bird Statue again if you feel like, then leave through the door on the east side of the room.
