I have cleared the area and in the middle of the courtyard it looks like there is a book. I see the gold icon of the book here but I don’t know how to get down to it. The water well nearby is blocked but can’t be accessed. Where is the entrance for the book?
I found it when I went down the edge of the cliff and used the hidden entrance down by the water. It brought me through a tunnel and straight to the book.
If you are in the courtyard, walk around the walkway surrounding the courtyard. A door will be at one end. Once inside, you go down some steps and end up at the book.
