fireproof notebook

Exploration Stage: Diggers' Stash
From: Martha
Description: Dr. Bertrand wrote down the unique order of the notes in a special secret musical notebook. I asked the spirit where it was, but he never told me. But I am sure you will find it.
Completed: There really is a secret to this book. There are symbols and pictures woven all over the cover. I think the book has a spell to protect the pages from fire.
