The Book of Shadows
The families big, old, magical book was a central part of the show. The book contained information on demons, vanquishing spells, incantations and much more getting the sisters out of many a sticky situation.
Over the course of the show the magic book practically became a character in its own right and while it never saw human form like Doctor Who‘s TARDIS or Charmed‘s very own Kit the cat, it did regularly throw tantrums or try and help the sisters by turning its pages on its own or even shocking evil doers to protect itself. Also, the Book of Shadows was most certainly one of the most sought after mementos for many a super fan!
