Considerably darker than any other area of the library, the Restricted Section is where the most dangerous books are kept; those that contain Dark Magic. This section can only be accessed with a permission slip from a teacher, which will be verified by the librarian. Upon verification, the librarian will retrieve the book. Only those studying on an advanced level of Defense Against the Dark Arts should have a reason for requesting such access.
To ensure that no one enters uninvited, a prominent sign floats above the entrance to this section:
Quote:
Do Not Enter. Any attempts to do so will lead to punishment. In addition, a locked and barred gate, protects the books.
