Final Round

I can fly without wings. I can cry without eyes. Whenever I go, darkness flies. What am I?

I have a heart that never beats, I have a home but I never sleep. I can take a man's house and build another's, and I love to play games with my many brothers. What am I?

It can’t be touched and can’t be felt. It can’t be seen, or heard, or smelt. It lies behind stars and under hills, and any empty holes it fills. It comes early and follows after, ends life, and kills laughter. What is it?

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I ?

Who can finish a book without finishing a sentence?
