Note: This is my first attempt at fan fiction, so please be honest with how bad my writing and grammar are, since I've never done this before.

Nopony knows where it came from, or what it is. It exudes wrongness to anypony who looks at it. This sphere of stone appeared out of nowhere, and overturns so much of what the ponies believed to be true their whole lives.

Sombra never realized this would happen.
Usually a villain is suppose to be defeated, right?
So, why did he, well...win?
Even he was shocked to see the crystal heart in his hooves. Never in a thousand or so years did he think he would pull this off; that he would actually...win.
So, what will he do now? Just rule over everyone and enslave all of pony kind? Or Perhaps kill the princess and mind control that purple unicorn and her friends? Or maybe have some common sense and figure out just how he will deal with all of this in the long run? With all these questions, he knows one thing for sure.
This is going to be very awkward.

Luna, still a bit unhappy at Celestia for banishing her to the moon for a thousand years, wants to have a small, tiny taste of vengeance. To be exact, she wants to send Celestia to the Sun.

So what is Luna going to do first?

Ask Celestia for permission, of course. Complications eventually occur.

It all started with a simple question: What if? What if Luna had ponies who noticed the beautiful nights she created. Would she have turned into Nightmare Moon? Would she and Celestia rule together for a thousand years? Would Twilight meet the rest of the bearers of the elements and become friends with them? Now, with the help of a new magic spell that she created, Twilight is going to find out!

Welcome to the Lunar Republic!

Celestia is settling into being a princess. It’s a lot of work, but luckily Star Swirl is a big help, even if Luna isn’t.

Then she wakes up and over a thousand years have passed. Her sister was banished to the moon and came back, Star Swirl is long gone, and Celestia apparently has a small purple alicorn student.

What’s going on?

A spell gone wrong, Twilight, Celestia and Luna have no answer how to get back home to the Equestria that they know.
Instead, they're stuck in a place where things are similar, yet so different.
They're stuck in what Equestria could have been.
And all they have is a book and their memories to help them.

This is my first attempt at a full on chaptered story. So whether it turns out bad or good we'll have to wait and see.

Something has happened and Twilight finds herself in a strange and dark new world. The Bipeds here have strange magic, advanced technology, and a lot of problems. She needs a few friends, and they just might need her. WORM crossover. Deadpan29 has created some great supplementary material that is canon to the story.
