Hi, thanks! good catch, you are right it should be 14.
Good observation. The secret passage in the Library is a vertical ladder that goes down, behind the bookshelves. I thought the drawing was enough info but you are right it's very small.
I should add that it connects with 15.Tapestry Hall.
Also, perhaps I can add a small zoom-in circle like I did in other details of the dungeon.
