This story was written for the Everfree Northwest 2014 Writing Competition. Its stipulations stated to "Show an established My Little Pony villain or rival either being redeemed or showing them in a positive light." There was a limit of 1000-3000 words.
I got the idea for this story during my Modern Physics class. I was sitting there, looking out the window, and the idea for the opening came to me while I watched the clouds. I wrote that out then and there, but then wasn't too sure how to proceed. So I kept writing what came to mind, and later that evening, I realized exactly what to write. That's the first time that something like that has ever happened to me. Anyways, I hope you all enjoy.
