Our contemporary finds himself in the Dark Ages. The ancient world is dead, and the Middle Ages are just beginning. The Roman Empire is strong and is at war in the east with the Persians. Its population calls themselves Romans and does not suspect that they live in Byzantium. The Empire cannot control its former lands, and therefore strong and predatory kingdoms of the Franks, Goths and Lombards arose there. The Slavs emerge from the deep forests more and more boldly and seize new lands in a stormy stream. GG finds himself in the worst possible situation. He is a slave, and according to local laws he is a talking property. Will he be able to use the knowledge and skills that life in the twenty-first century has given him, or will he remain in captivity? There is a chance, and a considerable one. The harsh life at that time provides extraordinary opportunities... Many thanks to Dmitry Alekseev, who on his resource collected excellent material on life in the Middle Ages, management and weapons of that time. Link here: From the author: To understand the historical context of this era, I recommend reading my series “The War of the Two Queens”. It describes the forty years of civil strife in the kingdom of the Franks, preceding the events described in this book. In fact, the last chapter of the series directly flows into the first chapter of the book “Merchant from the Future”.
