Bogatyrs guarded Ancient Rus. In the people's memory, they remained heroes, but in fact they were mercenaries, among whom there were both noble and unscrupulous superhuman warriors. The time of their exploits passed when the Tatar-Mongolian army of Kalin Tsar came to the Russian lands, who defeated the army of heroes and subjugated Rus to his will. And since then the knights began to live secretly among people. They rose to defend the fatherland only during enemy invasions and major military conflicts: in the Northern War with the Swedes, in battles with Napoleon, in the battles of the Great Patriotic War. But there were fewer and fewer heroes, only a few warriors have survived to this day, who will again have to unite.
