Wanting to punish a headstrong subordinate, who not only miserably failed an important task, but also does not consider himself guilty of it, the Okhrana leadership sends senior foreman Steini to a new duty station in the most remote place of the Empire. Without suspecting that peace and quiet at the Ostmor separate customs post is now under threat. Because the guard and the restless demon, who are toiling from idleness, cannot help but stir up the whole neighborhood. One good thing is that the senior foreman, Carridan Steiny, does not forget about his duty. And he serves honestly. Although, according to the demon, this is where all the problems come from... However, the horned benefactor does not lose heart, because he is always happy to help. True, only in strict accordance with the most important demonic rule: “What is unnecessary is free, and what is necessary is only for money!”
