He is a powerful wizard and "Guardian Master" who struggles with an intense bloodlust. The narrative follows his internal and physical conflicts as he hunts and devours predatory creatures known as Stalkers, all while desperately trying to suppress his darker instincts to live a normal human life. While the story heavily incorporates ancient dark fantasy elements—such as centuries-old wizards, magical secret societies, and monstrous, predatory creatures—these supernatural conflicts unfold in secret right beneath the surface of modern human society. The primary tension of the series relies on Caine Wolf trying to blend into this normal, everyday human world while battling his hidden magical instincts.
