Andrey, an ordinary programmer from St. Petersburg, suddenly begins to see frightening dreams in which he sees destroyed medieval cities filled with demonic creatures. When the lines between dreams and reality cease to exist, Andrei finds himself drawn into events after which his life will never be the same. Xermet, a battle-hardened warrior of the Gakruk Kingdom, has been fighting for the survival of his people for several years now. Dark magicians, mentions of whom were preserved only in ancient manuscripts, unexpectedly struck again. His world lies in ruins, and the battle seems lost. However, Andrei and Xermet have much more in common than they can imagine. Together they will have to understand the true nature of the universe, learn about the shared past of both planets and save them from the invasion of demonic creatures.
