After being imprisoned in a rebellion, Emperor Ian is sent a century into the past and awakens in the body of a bastard son of the Margrave family. Ian, a wizard of the Bariel Empire, becomes emperor at a young age, but his nephew’s rebellion leads to his imprisonment. The wizard Naum saves him with forbidden space-time magic, sending him 100 years into the past. There, Ian inhabits Bastard Ian, an illegitimate son of the Margrave family, which went extinct a century earlier. The younger Ian is about to be taken hostage by barbarians, as a bloody conspiracy begins to unfold around him.
