The world of a millennium ago. The last retreating glaciers, the first legendary empires, the mythical ancestors of the Finns and Slavs and the miraculously preserved relics of much more ancient eras - all this is the world of the great Aratta and the wild lands surrounding it. Fifteen-year-old prince Ayur goes on his first real hunt in order to defeat the great beast in single combat. His path lies in the Creeping Mountains, where mammoths and bloodthirsty saber-tooths still live. In his desire to test himself, the young man does not even imagine how far he will have to go on this path. What he has to face is much worse than any wild beast... Young Kirya from the Ingri forest tribe, living on the outskirts of the inhabited world, accidentally discovers a magical gift in herself. A simple clay whistle in her hands acquires extraordinary and sometimes dangerous power. How to use this power, especially when strangers invade the forest lands and the familiar world begins to collapse right before her eyes?
