Chrysalis, the last Queen of the changelings, is dying. With her death, her children will die, and the changelings will cease. She has one final plan, a coup to save her race, her children. She must make a new Queen, one strong enough, and smart enough, to save her people. It will be her legacy, and her greatest achievement. Too bad she never asked Twilight if she wanted to help

Dark tag added just to be safe, but its a "light dark" if that even exists.

In the far reaches of Canterlot Castle, high above in the towers lived the archmage. Everypony knew her, yet few had met her.

Twilight Sparkle sighed, having teleported away another noble seeking favors before reaching the top of the stairs for the second time today. They never learned. As the archmage, she already dealt with political squabbles far too often without inviting them into her home. Aside from personal favors for Celestia, she did what was required of her position and then returned to seclusion and research.

The nobility grumbled that no archmage should be a commoner, and Twilight’s disrespect toward them proved it. Each and every time they were forced to bow to her, they hated what they saw: the position, the status, the deference.

Was she not powerful? Was she not great?

Twilight, now reading through dusty scrolls and long forgotten tales, wrote in her notes — notes gathering dust of their own. A brief thought flashed through her mind.

Am I not powerful? Am I not great?

And then Twilight picked up The Tale of the Royal Pony Sisters.

Defunct side stories told in Across the Boundary. They can still provide a little context, but when in doubt, the main story here is canon.

Well, it was supposed to be a nice relaxing trip to Canterlot. But that never happens does it?

First, I sprain my hoof by falling down a staircase. I'm not even in Canterlot yet. Then once we get there, Discord shows up when we're greeting the Princess and acts all funny towards me. Then, to top it all off, as I'm reading a nice book, I get sucked back in time against my will. Isn't life just wonderful?

Wait.

...

Did you say Starswirl the BEARDED?!

Teen only because it might have some deeper, kinda darkish stuff in the middle. Not too dark or anything, don't worry! :D

DiscoLight (or Twicord, whichever you prefer) only if you're really looking for it. For those of you who don't like the ship, or don't like shipping in general, don't worry. No romantic moments or anything. :P

Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins. 

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?

Beware of spoilers in the comments!

After the changelings' failed invasion of Canterlot, Twilight tries to soothe some of Ponyville's rampant paranoia by casting a spell to prove there are no imposters hiding in the town. But her spell leaves her in an alien body, facing a mob of angry ponies who just don't believe her when she says she is Twilight Sparkle.

Or, at least, she was Twilight Sparkle, anyway...

As Twilight Sparkle awoke one morning from uneasy dreams, she found she had been turned into a changeling.

How has she become a changeling? How will she adapt? How will her friends respond? And what new terrors will her metamorphosis bring?

Thanks for everything guys. I never expected this thing to get so popular. I need to rework the second chapter, but it looks like there's going to be a blue moon every Friday for a while yet. Thanks again for your support and please keep reading and reviewing!

EDIT2: I've updated the character list again, a little preview of the second story arc...

EDIT 3: Just doing a quick character update to account for changes made to the next Arc...

Princess Twilight has taken her place as the newest member of the royal family. After some time Discord becomes Twilights personal advisor and they are driving each other crazy. In more ways than one.

With their partnership comes many changes to Equestria and Twilights political power has started overshadowing the Royal Sisters.
This was Celestia's plan all along, but it doesn't stop there.

Professor Discord starts receiving unwanted attention from the new student of Celestial Academy, Twilight Sparkle. As Twilight spends her days trying to unravel the mystery surrounding the Draconequus, something watches from the shadows with malicious intent.

"Three's A Crowd" endcap. In which Discord hates his life, Cadance is a bit of a troll, and Twilight learns an important lesson about friendship and the concept of negative vs positive attention. Also, a draconequus makes a tolerable kite when necessary.
