When books suddenly start to go missing from ponyvilles local library. The resident librarian goes on a rampage to find the culprit.

Displaced Fic
You know the deal, probably to the point that the descriptions themselves have become cliche, but here it goes. I went to a convention as Roxas from Kingdom hearts. After dealing with the merchant, I found myself in the land of Equestria from My Little Pony, around the time when Discord was first imprisoned. Being an avid fan, I decided to help Celestia and Luna imprison him. After that, we became friends. But after certain painful events, I found I couldn't face them anymore. So I left. And vowed never to return.

Uncle lives a very fulfilling life at his antique shop. It's peaceful and quiet for the most part, just how he likes it. Of course, he's a skilled chi wizard, so he knows better than to actually let the universe know that he's content. So he complains.

A lot.

Then one day, a basket containing three infant magical ponies arrives, and his peaceful life goes out the window...to be replaced with, perhaps, something a little more than contentment.

The universe, apparently, is smarter than he gave it credit for, because now he has "Three More Things!" to complain about to hide just how much they mean to him.

What will happen to everyone's favorite changeling Royal Guard when Chrysalis comes to town?

This is my take on what will happen 10-12 years in the future of the fantastic story The Changeling of the Guard by vdrake77 when A Canterlot Wedding takes place.

Idol Hooves holds a special place in Equestria. He's probably the only exiled changeling to serve in the Royal Guard, or at least, that's what he expects, as exiles don't really broadcast that fact. However, it's well known that Princess Celestia loves all of her little ponies, and her guards perhaps more so, and that makes it one of the best ways for a changeling to discreetly feed.

But how does a changeling even get there, let alone get exiled in the first place? For that matter, why would it ever go to Canterlot? Set a number of years before the series proper, before Luna’s redemption, Idol details how he was exiled, the ponies he’s met, and the series of misadventures that led him to joining the Royal Guard, and should continue a good ways into the series, as something of an alternate perspective.

Soon, he’ll have to deal with a boisterous new princess to serve and a royal wedding in the works bringing a third to power. Will his old instincts bring this new life crashing down around him? What precipitates Chrysalis’s ill-fated assault on Canterlot? Is it really so wrong for a changeling to enjoy good craftsmanship to an obsessive degree?
