Aliens arrive in the Solar System—beings who outpace Earthlings in development by tens of thousands of years. They settle on the smallest continent, and then begins the infiltration into human civilization of the Middle Ages. At the same time, a mind from our modern world enters the body of a young man, the son of nomadic people’s ruler—while the original host, a person from the present who died in the zone of a special military operation, is no longer alive.
The hero learns that an unknown group rules the world through religion, and he faces unthinkable technologies in medicine. Still, the hero tries to survive in this world by arranging his life according to the conditions he’s given.
You can learn about the hero’s adventures through the narration of a fictional story.
