Twilight Has Grey Hair

"How is this possible!? Where!? When!? I'm too young for this! Oh, Cadance, the breathing technique isn't working! How can somepony as calm and collect as me get grey hair!"

Twilight seems to have run into an unexpected disaster. The mystery that Twilight falls prey to goes on unsolved, but isn't there at least one pony out there willing to help this distressed unicorn? Maybe three?

Cover art by me, I guess. I don't really know if I need to link myself to my own story.
