The fifteenth century was a troubled time in Rus'. The Tatar yoke still weighs heavily, while the divided and weakened principalities feud with one another instead of uniting against their common enemy.
But even in these difficult days, life goes on. A merchant named Anikey decides to hire an assistant and takes on a small, by-age, but very capable boy—Misha Lobanov. However, Anikey could not have imagined just how clever and gifted his pupil would prove to be. Soon the merchant’s affairs began to soar, and the boy started looking into such far horizons that the merchant himself had never even thought about. Only then did this elderly trader realize he had found not just an assistant, but a future owner of the shop.
But does young Mikhail think only about that? After all, Rus’ is unsettled, and fate more and more often puts him in contact with a centurion from the Vyatka troops, Kostya Yuryev, who invites the young man to join the ranks of warriors preparing a raid on the Tatar capital.
