Deurums. Prince of Chernobog

Moscow, 25th century.
The world after a global catastrophe. Ancient Slavic gods have returned to our world after long wanderings and punished people by taking away the sun. The only hope of humanity is the mages, deurums, messengers of the gods... on Earth.
Dea, a police lieutenant and low-level mage, maintains the balance of the forces of nature. Without people like her, the world would have long since perished in the underworld of Chernobog. One day, during an investigation, she encounters a mercenary who lives outside the law. Only he turns out to be Prince Gabriel, the messenger of Chernobog, who escaped from a cruel father and the burden of power...
Representatives of different forces, of Darkness and Light, must unite in the fight against a common enemy. Will they, so different, be able to get along?
