When Celestia went on sabbatical into the west, she promised Twilight it would be only a couple of months. A year and a half later, the sun resists control, the country is in ruins, and her teacher is lost in the wilds. Twilight has become the apostate, her faith in her teacher and her teachings waning. In the wake of tragedy, her resentment blossoms into fury and she vows that something must be done. Shadows gather around Canterlot, and old things that should not have been awakened are on the move. The Student goes west, her hope restored by friendship and righteous fury.

The night, at long last, is passing.

Celestia wants Twilight and her friends to loosen up a little bit around her. Luna just wants to try the hard cider. During a surprise visit to Sweet Apple Acres at the tail end of cider season, Princess Luna has just a bit too much to drink, and when she makes a rather inappropriate joke, Twilight comes to the very uncomfortable realization that she has never seen Celestia excuse herself to use the restroom.

On a dark and foggy night, Twilight receives some visitors. That is the last anyone ever hears from her.

All of of her friends and family go on a desperate search to find her, but it is all to no avail and they give up on the search. Years turn into centuries, eventually adding up to a thousand years since her disappearance, but Equestria has never forgoten her.

After a thousand years, Twilight returns with no memory of who or where she is. Her captors give her a new name and title for her, but not only that, but she has also been given an assignment, to destroy Princess Celestia.

But is there something much more to her captor than just ruling Equestria? With the help of a group of friends, one princess will see just how magic can be used, whether for good,

or evil.

I would like to thank 1Jaz for this great drawing. Well done man!

And a big thanks Ephraim Blue for editing this story!

An alicorn who wishes to repair a friendship in any way possible finds herself aboard Equestria's largest space station. Her goal is to keep things friendly with her old friend, to avoid relapsing into the past and ending up alone. As Twilight attempts to fix the fence, the station becomes contaminated.

There is an Organism...big, relentless, aggressive, and extremely deadly that arrives on the once friendly station, causing chaos and turning the friendly atmosphere into a war zone. Twilight, who has no experience in mechanics or maintenance, has to fix the station.

Watch Twilight as the hunt begins, as ponies turn on one another, and as a friendship slowly begins to crumble. Could you tell me how long it would take you to...sign out?

The dragon-pony hybrid story has always interested me, so this is my version of if Twilight sparkle was a dragon-pony hybrid.
Her mother is a dragon OC I created and her father is also an OC, so keep that in mind when reading the story, and Spike will be her younger half brother.
In this story, we will be following the life and times of Violet, then her hybrid daughter Twilight, and Spike, I'm going to be including some parts of the show, like holidays, major events, and even a twist on how she got her cutie mark. Also since a lot of episodes in the show are season based I'm going to rearrange a lot of episodes to make the seasons make more sense.

Mistakes.
Everybody makes them.
Not all mistakes are equal.
Some are far less costly than others, and some can spell disaster.
When mistakes have such disastrous effects that you know it was not meant to be this way, you try to fix them.
When alicorns make mistakes, the fate of the entire world can change on a whim.
I am Princess Twilight Sparkle. I know where it went wrong.
I may not be able to undo my mistakes, but I can prevent them from happening to myself again.

Twilight didn't know what came over her. At one point, she was having a wonderful tea party with her friends, and the next thing she knew, she was trying to kill the princesses.
This could have something to do with the fact that nopony would listen to her at her brother's wedding, everypony thinking she is crazy, or even the fact that Discord was set free without anypony noticing.
She finds herself at Celestia's court, facing crimes she didn't commit.
"Twilight Sparkle, for stealing the Elements of Harmony, attempting to kill me and Princess Luna, and Betraying everything you were supposed to protect, you are hereby banished from Equestria, never to return!"
Celestia's words continued to ring in her ears as she followed the road out of Equestria. She would never see her friends again.

An accident causes Celestia to end up in a frontier town amid the wilderness without her memories, leaving Twilight Sparkle feeling devastated as Luna tries to help her—plus, there's a little mystery to solve.

Certain TAGS that apply to this story are spoilers and will be added only when the relevant chapters make them unavoidable—there IS a mystery to reveal in due time, after all. Have fun figuring it out

My other two stories are pretty good sized and I've been bouncing between them on posting chapters. But since those chapters are rather large and highly detailed, I thought to post this in increments to pass the time. This is story is completely unrelated to my others and it has considerably few chapters, with a new chapter to be posted about 1/wk.

Okay, a few words about the points to award:
1 point for the first one to guess the origin of the "crossover" in this story -- that's way too easy.
5 points for the first one guessing who Tumbleweed is from that "crossover" series -- not so easy
10 points for first one who guesses Filly's partner prior to Ch 6;
5 points for first one to guess who she is if no one has by Ch 6 but before Ch 7;
0 points if after, because the answer will have been given.
25 points for first one who guesses the overall mystery of the story prior to Ch 10;
15 points for first one to guess what's going on if no one has by Ch 10 but before Ch 11;
0 points if after, because the answer will have been given.
Again, just have fun

oh, and a bonus of 20 points to whoever can guess the "crossover" that's referenced in "Night the Lights Went Out in Canterlot"

Twilight Sparkle and her friends get invited to the Appleloosa Friendship Festival as the guests of honour.

No one informed Twilight that there would be cheese. So much cheese. Ooey, gooey, melty cheese inside of a toasted tortilla.
