Sky Machine City

I met an alien named Gray Prince. She has taken me to more than a hundred alien planets, and she has also shown me life and cities that do not live on planets. Higher beings have repeatedly created and destroyed life in the solar system, until they came to the earth, established a mechanical city in the sky, and created beast-headed giants. Human beings were the result of being forced to stay after resisting higher beings. The Gray Prince only said one thing to me: Human beings are never able to stay because of luck.
