What happens if in the distant past it turns out to be not a special forces paratrooper who is able to knock down propostats in packs with his bare hands, not a chemist-physicist-engineer who is ready to spawn technical progress on fear of enemies and on the joy of his beloved, but an ordinary, in general, person who has "behind the soul" only knowledge of control theory, but quite rich life experience? What will happen if he is in the body of not a prince, not a hero, but a teenager from the Pripyat forest wilderness? Or maybe there are more important and even saving things than mordoboy qualifications or the ability to obtain nitroglycerin from improvised means in the field? Suddenly, despite the difference of nine centuries, people will still be the same people as contemporaries, and basic values: love, honesty, conscience, family ties, patriotism (may the "common people" forgive me) - will remain the same?
