The demon is defeated! The long bloody struggle with the forces of Darkness, which cost the lives of many, is over. The inhabitants of the kingdom of Corona owe their victory over Evil primarily to the brave Jilsepony and the power of her magic stones. But even they could not protect the warrior maiden’s faithful companion Elbrine from death. In an effort to heal mental wounds, Jilseponie goes to the north of the kingdom, where he hopes to gain new strength. However, trials await her there too; the inhabitants of the northern lands die in thousands from an incurable disease. Where did such a cruel plague come from? Are the forces of Evil again raising their heads? What if the spirit of the destroyed demon still hovers over the world? Bewilderment and horror engulf the inhabitants of Corona. Everyone is sure that only the magic of the stones and the gift of a healer that Pony possesses can defeat the terrible illness.
