In a world parallel to ours (with slight differences), the soul of a young elven magician (only a thousand years old) enters a human body. The only problem is that he is deprived of magic and longevity and is locked in the body of a human, who has been given a measly forty years of life. A short moment, compared to the lifespan of a firstborn, during which you need to return at least one of two things: magic or longevity.
