There is a portal on Earth to other worlds. Three close friends—Seryoga Voronin (Vорон), Petya Kalinin (Pуzyрь), and Lenka Zvonaryova (Fairy)—find this portal and end up in a magical world. In it, people live side by side with elves and minotaurs. There are also secret cults and knightly orders. Magic is a profitable and respected profession. Earthlings quickly find their place in the sunny world of a magical medieval—largely thanks to the knowledge and skills they managed to gain on Earth. Puzyрь becomes a guardsman (with the prospect of being knighted), Fairy enters the Academy of Magic, and Vorон… Voron turns out to be in the School of Thieves.
After joining their new reality, the heroes realize too late that it is not virtual at all—that real danger threatens them. Surrounded by non-humans and demon worshippers, pursued by a powerful secret order, they nevertheless must carry out their mission.
