The story is staged in the distant future within our own Milky Way Galaxy, approximately in the 35th century. Unlike other science fiction stories, there are no alien civilizations. A portion of the galaxy is filled with terraformed worlds inhabited by interstellar traveling human beings. For 150 years two mighty space powers have intermittently warred with each other: the Galactic Empire and the Free Planets Alliance.

Within the Galactic Empire, based on 19th century Prussia, an ambitious military genius, Reinhard von Müsel, is rising to power. He is driven by the desire to free his sister Annerose, who was taken by the Kaiser as a concubine. Later, he wants not only to end the corrupt Goldenbaum dynasty but also to defeat the Free Planets Alliance and to unify the whole galaxy under his rule.

In the Free Planets Alliance is another genius, Yang Wen-li. He originally aspired to become a historian, and joined the military only because he needed money for tuition. He was rapidly promoted to an admiral because of his demonstrated excellence in military strategy. He becomes the archrival of Reinhard, though they highly respect one another.

As a historian, Yang often narrates the rich history of his world and comments on it. One of his famous quotes is: "There are few wars between good and evil; most are between one good and another good."

Besides the two main heroes, the story is full of vivid characters and intricate politics. All types of characters, from high nobility, admirals and politicians, to common soldiers and farmers, are interwoven into the story. There is a third neutral power nominally attached to the Galactic Empire called the Phezzan Dominion, a planet-state (city-state on a galactic scale) which trades with both warring powers. There is also a Terraism cult, which claims that humans should go back to Earth, gaining popularity throughout the galaxy. The story frequently switches away from the main heroes to the Unknown Soldier fighting for his life on the battlefield. Less...
