Fly me and you’ll lose a friend, Yet I am happiest on the wind. I pull against what holds me tight, A rebel shape against the light.

I have existed millions before humans. I am hard. I am a home that humans collect.

I follow you in sun's bright gleam, grow long at dusk, vanish in dream. No weight or voice, yet always seen, light chases me to nowhere's stream. What am I?

What has roots as nobody sees, is taller than trees, up, up with it goes, and yet never grows?

I travel the seas but never feel the sun. I carry many souls inside my metal shell. I dive like a whale but breathe like a machine.
