By a mistake of fate or a guardian angel, an earthling ends up in the body of a person from another universe. Unfortunately, the owner of this body has not gone anywhere, and now two different personalities have to share one body between them. One controls the body during the day, the other at night. One strives to survive and succeed, the second wastes his life and finds himself in all sorts of emergency situations. Thanks to Artyom, an earthling, they manage to survive and even get assigned to command a border outpost. It's very uneasy at the border. Savages constantly attack and plunder settlements. Artyom repelled one of these attacks with the help of his reiters. And life seemed to be getting better. But his connection with the awakened new guardian was detected by the dragon - the only Guardian of this world. Now the earthling has become very dangerous for him.
