Rus’ in the 14th century. Princes fight for the expansion of their holdings, proving by force of arms their right to the grand prince’s throne. From the Oka to the Volga, the flames of internecine wars blaze—while only Novgorod, with its arrogant disdain, looks down on the foolish ambitions of rulers. It is precisely into this setting that our contemporary is thrown. He has just one very pragmatic desire—to survive and return back—but circumstances lay down their own conditions, forcing the hero to take up arms, and fate grants him the Bear Castle.
