I got dragged to Equestria by pure accident due to an experiment gone 'wrong', roughly forty years before Nightmare Moons' arrival.
No matter what I do, as a pony-changeling hybrid, something will change with Equestria. I just hope I don't doom the country before Nightmare Moon even arrives... Or worse.

This is the first story I ever tried to write professionally, so there WILL be errors, for that, I apologize in advance.
I'm editing and proofreading it on my own because I literally suck when it comes to using this site competently.
Lastly, I am a slow writer due to IRL getting in the way but I will try my hardest to settle the story down whether it's popular or not.

Fair warning, there may be spoilers in the comments.

Thank you to Little Tigress for the fantastic cover art.

When I agreed to be sent to Equestria I didn't read the fine print. I'm the wrong age, the wrong sex, and lost in the wilderness.

King Sombra came from an old age, a time where darkness and evil were prevalent across the land. The Princesse's power and influence were weaker in those days, for the land of Equestria was divided amongst many kingdoms of lesser Princesses and Princes. But out of all their ruling neighbors, The Four Shepherds held the most power of all, even threatening Celestia and Luna's kingdom. However, all of that changed when they vanished for a thousand years, ushering in a new era of peace and prosperity. Until that is, when the Crystal Kingdom reappeared, along with one of the Shepherds. King Sombra, however, was thankfully vanquished swiftly, but the following peace of his defeat would not last as long as anypony might think. A new force sets its eyes on the recently coronated Princess Twilight Sparkle, one that seeks to restore a lost heritage and remind the land of who is the true owner of the night. For when one evil is smitten, another appears in its place. And King Sombra was only the first in line.

Set before Season 4

Special thanks to my editor Ladrian for his diligent and superb work. I wish I had him when I first started this story because maybe then the early chapters would have been much better.

Special thanks to Stanku for revisions and prereading this story. It would be at a much worse state had it not been for his detailed opinions to each and every chapter, and letting me know where I can improve.

10/2/2014 : Woah... it's on the featured list... *cue squealing and fist pumping* THANK YOU ALL SO MUCH!

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?

Comedy Tag added as well
And changed the character tags a bit.

Nightmare Moon has returned. Princess Celestia lied and betrayed her star pupil, Twilight Sparkle, leaving her woefully unprepared to fight the Queen of the Night.

But when she fails, rather than disposing of her and the ponies that tried to help her, Nightmare Moon sees an opportunity and a necessity. Having been locked away for one thousand years, who better to help her solidify her rule and keep Equestria from collapsing, all while rubbing it in her sister's face, than her own betrayed pupil?

Monster attacks. Crime. Illegal hallucinogens made from electric fruit.

They say things didn't use to be like this. They say things were different, before Luna came back 60 years ago, but Detective Hard "Hardy" Boiled of the Detrot Police Department has never known any world other than that demarcated by the seedy streets of his beloved decaying metropolis; a world in which the coroners sing and dance, surveillance bugs have personality disorders, and the Chief of Police is a scarier entity than most of the eldritch things the city attracts.

The grey unicorn who turned up dead outside the posh High Step Hotel seemed like just another case, but her missing horn is the pointy tip of a very large and nasty iceberg. It's up to Hardy and his friends - a rejected monster hunter, a psychic cab driver, and an underground antiques heir - to find out what’s going on in an investigation that promises to stick more than a cupcake into the very eye of Detrot.

Especially if Hardy has anything to say about it.
