Once every ten years, Forbidden Battles take place between the Guardians of Light and the Guardians of Darkness. People are not allowed to participate in them, but if a person offers his eidos, he can fight with anyone who accepts the challenge. Methodius does not need anyone, he only needs one dark guard - Jaf. After all, it is he who keeps the medallion in which the soul of Ares’s wife, the teacher of Meth, has been languishing for many years. Buslaev promised him that he would get the medallion, no matter what the cost. But how to defeat an enemy fighting with an invisible weapon about which nothing is known? Or will Methodius not win this battle? The situation is complicated by the fact that Irka, the junior manager of the necro department, whom Mamzelkina sees as her successor, will have to pick up the person who died in the battle. And you can’t refuse - the lives of Bagrov and Babani are on the scales.
