In the summer, vacation begins at the College of Magic and Witchcraft of the Marquis de Guyac. The young sorcerer Bitali Kro is left alone and, out of boredom, succumbs to the naive blackmail of a mortal girl who wants to earn some money with the help of his talents. Bitali could not even imagine that this small pampering would quickly develop into a bloody war with the ancient witchcraft family of the powerful Counts de Courtenay. Five young magicians and two witches - against an entire army. However, the blood of the Dark Lord flows in Bitali's veins. If he remembers the secret of his ancestor, he can win.
