Librarian: Tidy up the Arcane Library - TRUE LIBRARIAN CHALLENGE LONGPLAY (Anti Magic Master)
A true Librarian:
1. Never treads on a book (even if the game doesn't really know if you do or not)
2. Never tosses a book to the floor
3. Always puts a book on its correct shelf, no exceptions
All of this and getting the Anti Magic Master achievement... this took a LOOOOOONG time.
