The word “Itihasa” is translated from Sanskrit as the expression “That’s exactly how it was.” The earth of people is in danger. The army of the deceitful ruler Tögyünchi Kagan is trying to break through to a mountain lake, in the depths of which lies an artifact capable of destroying the entire world. The priestess of the northern tribe, Dyalama, is hiding something, and the demon catcher Taragan is already preparing his weapon. How to change your fate and stay alive? How to understand who is a friend and who is an enemy? Or maybe something more important is happening, and someone is controlling it all? To understand this, the demon Alhagar will have to not only enter into battle with ominous creatures, but also look into himself and listen to his heart. The book is based on materials from ethnographic research and the epic of Ancient Altai.
