Some ponies just don't have any luck.

Twilight Sparkle is one of them.

Sure, other ponies might say she's the luckiest pony ever, being the personal protégé of Celestia, a well known pony in all of Equestria.

What they don't know, Twilight Sparkle isn't Twilight Sparkle.

Everything was perfect, her cover has never been blown. Until that one fateful day, the day Shining Armor, Twilight's brother, should have been married, the day of the changeling invasion.

The cleansing wave of love that send every changeling away...

There are only three ponies who know the truth, Twilight Velvet, Night Light and Twilight herself.

Edited by Jphyper, thanks for that.

The failed invasion of that mad queen, Chrysalis, rocked the changeling community. From the hives nestled outside Equestria, to their kin living in peace within, they watch those colorful ponies eye one another with suspicion and let themselves be swallowed by fear and distrust.

A gamble by Princess Celestia has summoned forth the diplomat to the Seekers, the one changeling who may be able to ease tensions between their races and restore balance. The Bearer of Magic has been summoned after a century of peace.

And, like her mother before her, Princess Twilight Sparkle will answer the call.

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:

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!

You needed love, and I gave you some. Now, I am your mother. I love you as you love me. My resentment for your race didn't stop me from helping you.

And that was far from a mistake.

A mother will do a lot for her child, even give them up if it meant them having a safer life growing up, despite the obvious pain that comes for the parent.

That pain is something Queen Chrysalis has gone through for eighteen years, but now the time is upon them, and she wants her daughter back. Even if that means invading Canterlot during a royal wedding.
