Letter of Introduction

The Letter of Introduction is a quest item from The Legend of Zelda: Oracle of Ages. This letter is obtained by giving a certain Goron Lava Juice in the past. He can be found by traveling through the staircase south of the Goron Dance Hall. The letter is then taken to the first generation of Graceful Gorons, who then allows Link to dance with him. If Link completes the dance, he will earn the Mermaid Key.
