Stop and listen to them, my little pony. They have stories to tell. The moment they're born they're already in freefall.
They don't know when they'll land, but they know they'll meet their end soon, shattered to pieces and swallowed up by the earth. Celestia wanted to hear their stories too, once.
That's why She made your kind—the first pegasi were formed out of the clouds, just like the raindrops, but She gave them wings that they might live a little longer.
But you still won't live forever, my little pony. One day, you'll land for the very last time. So tell your story while you can.
