After covering an enormous distance, Maksim Serov, together with the pilot of a starship, reaches the outskirts of the Rus empire. In the 150 years that have passed, the situation has changed greatly: power in the Rus empire belongs to the Old Believers who were brought into Max’s world from 1913. From the north, a threat of invasion has emerged— the “Deutsche,” a people that originated from Nazis and local tribes. The only island where Max can feel safe is Berlin, which pursues a semi-independent policy. Max and the sect “Return” begin a difficult confrontation with the enemies looming over Berlin and the border town of Mechik.
