Prince, knight, close neighbor of the Grand Duke - a good list of achievements. The seventeen-year-old son of Prince-voivode Sergei Ilya is an experienced warrior, powerful, skillful, knowing everything that a voivode should know, speaking half a dozen languages, ready to lead ten, a hundred, and a thousand into battle, if necessary. However, he is only seventeen, and that is why feelings often outweigh strategic calculations, and passions turn out to be stronger than reason. But as long as there are those who are ready to stand side by side in a mortal battle, the enemies will not defeat the hero even in the most unequal battle.
