The Legend of Zelda/Walkthrough

This walkthrough uses the following notation throughout each quest. There are many things that are immediately available to you in the Overworld before you even set foot in the Underworld. You may choose to take advantage of that fact early in your quest, or wait until you have grown a little stronger instead.
