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