Do you think that the rare sparks swarming at dusk are fireflies? Is your neighbor's dog howling around the area? In your opinion, only faint-hearted fools go to their fortune teller neighbor Aunt Masha for a love spell? However, the world around us is not at all the way it is described in natural history textbooks. A werewolf howls in a city park, fireflies are the eyes of monsters hunting in the dark. And Aunt Masha, with a wave of her little finger, can cause a tornado and a volcanic eruption. You yourself are invited to work in the Service - an organization that guards the borders between the real world and the universe of magicians and monsters. From now on you are a Guardian... of whom even Aunt Masha is afraid.
