Long live the Queen.
An evil mastermind once attempted to take control of Canterlot for herself, if only for the understandable reason of being hungry and wanting to feed her army. She was quickly taken care of. But although nothing has been heard from her since and her army presumably since starved or perished, nothing can push away darkness forever.
When a select few Changelings return to Ponyville, their reception is understandably negative, and questions are asked. What brought them here? Why are they here? What are their intentions? These are only a few of their stories. Each of the Six responds to their arrival a bit differently, from sympathy to distrust to outright hatred.
All of this takes place over the course of one day, at the same time, through parallel perspectives.
