Answer:
I march before armies, a thousand salute me. My fall can bring victory, but no one would shoot me. The wind is my lover, one-legged am I. Name me and see me at home in the sky.
I can be quick and then I'm deadly, I am a rock, shell and bone medley. If I was made into a man, I'd make people dream, I gather in my millions By ocean, sea and stream.
Lighter than what I am made of, More of me is hidden Than is seen.
A house with two occupants, sometimes one, rarely three. Break the walls, eat the boarders, then throw away me.
A tiny bead, like fragile glass, strung along a cord of grass.
What is always coming but never arrives?
