He saves a young woman, but is almost fatally wounded. When he is almost well enough to walk, he discovers that the village doesn't have indoor plumbing or running water. The young woman that saves him grows firmly attached to him and helps him explore the small village. He builds a modern empire thousands of years in the past.
