Ponyville has become a very different place. While it is still slow and peaceful, ponies have come to realize Twilight Sparkle's regal status, and have flocked to the small town. Since then, it has expanded into a small city with its own guard force, with Rainbow dash acting as captain of the small group of soldiers. Everything is normal, at least until a group of illegal Changelings is found and it is revealed that one of Rainbow's friends may not be what they seem...

7075535 Gotcha
This is a really in interesting concept, and i’d love to see it continued!
It’s really good, and i like the way that it’s written. The characters seem really close to that in the show and movie, and I wouldn’t probably mistake this as something that’s had been written by one of the scrip writers for the show if i didn’t know any better!
