An idea borrowed from and inspired by a conversation with Pinkamen666.
If someone wants to draw cover art for this, I'd really appreciate it.

Queen Chrysalis had rejected reformation and escaped swearing vengeance following the reformation of her entire species. The world was saved and everypony could return to their normal lives.

Imagine Fluttershy's surprise when the dethroned changeling queen attempts to kidnap her again. It doesn't go according to either of their expectations and results in the starving changeling living with the quiet pegasus.

Fluttershy could terrify dragons and reformed a spirit of chaos, so surely she could help Chrysalis.
