The peculiarity of the atmospheric structure of the planet divided the world in which Ronan was born into three parts: upper, middle and lower. Being the richest man in the half-starved, backward lower world, a man ransoms a girl condemned to execution because she, Shilta, is a witch who sends pestilence and disease. In gratitude for her salvation, the girl becomes a powerful patroness of Ronan, helping to defeat death and find a priceless mineral, which the man spent many years searching for. But the more Ronan gets to know Shilta, the more clearly he realizes that he is becoming a puppet in the complex games of a mysterious girl, where the stakes are too high.
