There was no Germany at the beginning of the 17th century, but there was a huge Holy Roman Empire of the German nation, divided into hundreds of principalities, bishoprics, margraviates and other electors. And each of them has its own ruler, who only thinks about how to bite off a tastier piece from his neighbor in order to accommodate one of his many offspring. And if you are not a prince, but a princess, and an illegitimate one at that, then your destiny is to serve as a bargaining chip in politics and marry some third-rate feudal lord. But then something went wrong, and a girl from the future ended up in the body of one of these illegitimate princesses. Will our contemporary be able to survive in those harsh times when no one had heard of human rights, feminism and tolerance? And here, in addition, the world is not quite the same as in our history. In Rus', after the Time of Troubles, a certain Tsar Johann rules, on the roads of Prussia, in addition to robbers, you can meet the future Patriarch Philaret, in the Czech Republic an uprising is brewing, which will soon develop into a terrible thirty-year war. And one law rules everything - the law of sword and force.
