Ertostik and Idahar

The story

The khan of the underground kingdom of Bapa has started an insidious plan. He decided to swallow the Sun, the egg of the Samruk bird, and thereby create a world of eternal darkness on earth. Knowing that once in a thousand years a batyr is born who is able to stop evil, the khan, with the help of his assistants, does everything possible so that the batyr is not born and could not prevent him.
