These are the things that inspired the writer for the harry potter books, they were given to her by the pact that was made. They are far more dangerous than the books made them out to be, one look from a demon-dementor and even your very spirit will shy away in pain and suffering. I will not let them go cheap because the book made them look like sweet Sunday school children compared to the real thing. They can do everything the movies said and more. it is the more you have to worry about.
