While I'm happy to have finally gotten inside that cave on Plunder Valley after the +2000 hours of sailing, something dawned on me as I exited that cave: How DID people figure out where and how to open the door? Nowadays you just get the copy/paste of the positions needed at the tree but back then it was still a mystery. The final book mentions and by quote, "You might have found some of my pirate journals tucked away here and there. If you used the clues to open the door, bravo!"
Y-yeah...woo, I figured it out....no really, how did we do it??
