Ancient Rus' of the late 10th century. The campaigns of princes Oleg the Prophet, Igor and Svyatoslav the Great showed the whole world the military strength of the Russian state. And they made them afraid... Now clouds are gathering over the country, because the enemies of Rus' know how to fight not only with force, but also with cunning. If you can’t conquer a country where almost everyone knows which side to grab the sword from, then you can get entangled in a web of intrigue and force the rulers to voluntarily bow their heads. And in this difficult time, our contemporary finds himself in the body of a Varangian prince. Will he be able to survive in a world where the past has become the present? Will he be able to reverse the course of history known to him from books by rewriting it anew?
