Nok, the leader of the Reborn Guild, managed to break the curse, but the magical power contained in Cruor's oath is irreversible. If he does not fulfill part of the deal and does not kill Lina, the spellcaster and his beloved, he will pay for it with his own life. In addition, the truth about his past ends up in the hands of his worst enemy, which means only one thing - everyone who is dear to him is now in mortal danger. And their time is running out. Lina will do anything to save Nok. She learns about the fantastic beast Azad, who can help him. To do this, the girl and members of the squad will have to pave the way to the north. But when the moon rises over the dark grotto of death, what began as a hunt for fantastic creatures will lead to too many losses. They soon learn that their enemy is much more terrible and powerful than they could have imagined.
