World War I in full swing. In the west, Belgium fell, and German hordes are eager for Paris, an irregular maneuverable war broke out in Bosnia, in which a certain Mr. Seregin provides the forces of the small kingdom of the Balkan Slavs. But the main events take place in East Prussia, where the Artan army directly enters into battles on the side of the Russian Empire. There, Borodin's heroes are fighting the enemy, bending military success to the right side of history. And just at this critical moment comes the time of great diplomacy. Kaiser Wilhelm wants to meet with the Prince of Artan to find out "for what," as well as Emperor Nicholas, whom an ally who suddenly appeared is very frightening. And on the world map there are England and France, but no one asks them about anything, because since the victory near Tannenberg these are not subjects, but objects of world politics, and they have only to realize the depth of their fall and defeat.
