SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

When Twilight comes back from her week long visit to her brother's house, she finds out that everything has changed. Canterlot High is babbling about some magic girl from another world, but Twilight knows better. There's no such thing as magic, or portals into other worlds.

Right?

EDIT: Wow. Never expected the feature. And by the way, thank you for anyone who commented with a consructive criticism. I'll be reading as many as I can and keeping them all in mind for the future chapters as well as going back to edit the past ones periodically. Enjoy the story!

EDIT 2: Went into the first chapter and tried to fix up the 'Twilight did X' issue that many people commented on. (Thank you to those who did.) Hopefully it is a bit more readable now.

EDIT 3: After fan feedback on a massive error I made where Princess Cadence was an out of control lunatic, I rewrote the Twilight meets Twilight scene so that it flows better and actually stays in character. Thank you for anyone who made a comment about this, I am listening to your feedback and writing my future chapters accordingly. (If there are any more of these, I'm going to keep these in a changelog in a blog post.)

When Dialga and Palkia start to attack one another in Alamos Town, a Ponyta named Flare Blitz is caught in the crossfire. After falling into the dimensional rift, he finds himself in a strange new land filled with brightly coloured ponies. Flare doesn't know how he got here or if he can even get back home...

The question is, will he even want to go home?

Edit: So I finally got offa mah flank and started the re-write. I want to give massive props to Blazinblade7 for editing as well as my little bro, who is teaching me a great deal of authory stuff.
