The subject of protection from the dark arts was one of the most difficult at Hogwarts. Teachers for it were often changed because of the curse of Voldemort, and each of them had its own goals. The subject that Harry Potter and the other students of the School of Magic learned included studying methods of countering vampires, werewolves, dementors and other evil spirits. The subject was compulsory and lasted all five years, after which it was necessary to pass the exam. Of course, getting knowledge is very difficult without a textbook. Moreover, every teacher read the subject according to his own understanding.
All Harry Potter fans would not mind learning some of the subjects of Hogwarts. Want to have a Defense of the Dark Arts on your desk and take it with you wherever you can find both light and dark forces? Just order a protective case for your laptop in the style of the book’s cover of a cover, and no one will guess that this is a normal laptop, and not a magical handbook, where secret knowledge is hidden. Of course, such a cover will be a great gift to anyone who is passionate about Harry Potter and everything related to the work of J.K. Rowling.
