Ask Raquel if she can decode the directions

From Create Your Own Story

You turn to Raquel, who's standing by your side, and hand her the map. "Can you read this?" you ask.

Raquel looks at it for a long moment. "No. We need the key."

You wonder where the key to the code might be. Perhaps it's on the fleeing galleon.

Look more carefully at the love letters

Now that you've recovered the chest, resume your pursuit of the galleon
