Book of Magic and The Supernatural
"A book that is dangerous is read out of order or before one is ready"
This book details information about magical beings and supernatural creatures. Needless to say, a person willing to read a book like this would have an open mind, which is perfect for possession. For this reason, it is recommended that one take care while reading this book and any like it, as demons love to hide within and set magical traps for the unwary mortal to spring.
