Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!
In many ways, German and Italian history were parallel. Both came from ancient cultures dating back to classical antiquity, and both cultures had lived as the respective hegemon of their own regions for a period of time.
Italy, for example, had ruled as the supreme hegemon of the Mediterranean during the latter centuries of Classical Antiquity, while in Germany's case, the erroneously named "Holy Roman Empire" had served as, more or less, the supreme sovereign of Europe during the High Middle Ages.
But in this world, time alone remained undefeated. Whether you were a dynasty of kings, an unrivaled Empire, or a god himself, sooner or later, all things came to an end. It was simply a matter of time.
