30s of the 15th century. There is a civil war in Rus'. Lithuania is trying to absorb Russian lands. In the Horde, three contenders are vying for the royal throne. Rogue emirs are robbing Russian lands. The Russian land is groaning. Everyone is against everyone and everyone is for himself. Our contemporary, a self-proclaimed prince, is trying to settle into a new world for himself. The boyar's burden is heavy. Lies, deceit, violence and cruelty oppose goodness and justice, and sometimes you can’t tell what is evil and what is good.
