About the book: year / Athenaeum of Magic Grinchwild, built by Merlin's students, has never been the epicenter of oddities. But one year everything changed dramatically: kidnappings, ancient prophecies about Merlin’s staff and rumors about a new army of the devil’s executioner befall the inhabitants of the castle. Trying to protect themselves, the atheneum and their classmates, a group of young wizards find themselves drawn into an incomprehensible game with dark forces, the rules of which they do not know. And the war turns out to be more difficult than they thought when reading history textbooks.
