Princess Twilight Sparkle is at the top of the world with everything she's ever wanted... So what is that sickening feeling in her chest? And why does her reflection look so horrid?

This story was written under an hour in the Quills and Sofa's Speedwriting Group, for contest 58: Pride.
Big thanks to Seer, Dawn, Wish, Snow Quill, and Bill for their prereading of the story!
