In the middle of the sea-ocean stands the white-flammable Alatyr stone. It stands unshakably, unshakably for centuries and millennia. From ancient times it was customary that Perun’s creatures, Morena’s creatures and all, visible and invisible, hidden in Navi and walking among people, terrible and hiding their appearance in darkness, bowed to their shrine and protected it. No one suspected that the mermaid in love would set in motion a series of events due to which a crack would split the Alatyr stone from the very top to the base, and the entire magical world would be in danger of death. And werewolves and winged snakes, waterworts and witches, the midnight owl and the noon owl will come together to decide the fate of the secret world. Should he live or die.
