I'd appreciate if everyone could keep the YouTube embeds in the comments to a minimum. The sheer number of them is putting a bit more strain on my connection than I'd like. I'm going to start deleting any comments with 2 or more embeds in them.

Novel Tale is an author that's been living in Canterlot for about ten years now. That's a pretty good track record for a changeling. He's even included a changeling character in his latest book, and his fans have been loving his take on such an obscure mythological creature, especially his biggest fan, Twilight Sparkle. Things are looking up!

Then an army of changelings from another hive attacks Canterlot.

Now all of ponykind knows that changelings are real, and his readers are sure to realize that the changeling in his book was too similar to the real thing to have just been based on a myth...

earlier chapters have been revised as of 7/19/13 to be more inline quality wise with the later chapters.

Let it be known that there will be extensive changeling world building in the chapters to come.

Much thanks to Nyerguds for proofreading and to all my fellow tropers on the TvTropes pony fanfiction thread for helping me develop this from a vague idea into an actual story.

Cutie Mark Crusaders Time Travelers, yay! ...Wait, what?

When older versions of Apple Bloom, Sweetie Belle, Scootaloo and Spike appear from the future, Twilight and her friends are in for the time of their lives. The Crusaders have gone back in time on a mission that may decide the fate of time itself! They are fearless, they are resourceful, they... completely messed up right from the start, huh?

Now it's a literal race against time to set things right, as powerful enemies from the future attempt to claim the past for themselves. So join the Elements of Harmony and the Crusaders of tomorrow in an epic story of danger, hope, despair, betrayal, revenge, love and swashbuckling high adventure!

Just remember the golden rule: Time travel doesn't make sense!

For almost a year now, Trixie has been sending letters to Twilight. The only problem is, Twilight hasn't gotten a single one... until today. But now that she has, Twilight is left with more questions than she knows how to answer. Fortunately, she has a plan. Unfortunately, she doesn't know if that plan will work.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

"Have you seen a butterfly around here?" I asked Derpy one day. Next thing I don't even know, we're saving Equestria from the fairies in Fluttershy's chicken coop!

At the brink of dawn, something crashes on the Everfree Forest, causing untold amounts of damage and displacing many creatures that called the dark and foreboding forest their home. When the dust settles, a massive construct of metal is revealed to be the perpetrator.

Lyra Heartstrings, as well as the rest of Ponyville, approach the ominous edifice only to find there's something inside...

...And that something really doesn't like ponies investigating its home.

This is a one-shot, alternate perspective to the events that occur in the first chapter of Unknown. (Subject to change)

This story is a sequel to π

After Twilight Sparkle made her biggest secret public much earlier than she'd originally planned, the lives of the Element-Bearers and their closest friends somehow managed to become even more complicated than they already were. Yet despite the flurry of all of the added activity this brings, Princess Celestia decides to undertake a particularly ambitious project: the reformation of Discord. She delegates the task to Penumbra Noctis, who, more than anypony else, can empathize with the draconequus' situation, and who is therefore best suited to showing Discord the magic of friendship. On the surface, it's a very reasonable plan.

Unfortunately, Discord has never had much patience for reason.

This is the fifth and final story in The Petriculture Cycle. Reading the first four stories, which begin here, is highly recommended.
