There is a second castle now within the Wood, which only this book can truly reveal. In order to gain access to this castle, you must know the password at the gates. While the scribe who is recording the book does not know the password, there is one person who does.
Edmund was his name, at the time of this book's writing, but it might have changed since. He will ask you to give his full name. It is Edmund Eagleson. He will be bound magically to give anyone who knows his full name the password into the hidden castle.
Unfortunately, the whereabouts of this castle are still known.
