Over a thousand years ago, two royal siblings fought for the sky and were exiled, one by her sister's hoof, and one in penance for what she had done.

In the present Republic of Equestria, no one remembers them as anything more than legends and old pony tales. Save for one shy filly who fell from the sky one fine summer's day.

An Alternate Universe "What If" tale, reconstructing the beginning from a different angle.

Everything changes for Twilight Sparkle and her friends when a mysterious extraterrestrial ship crash lands in Equestria. When Twilight messes around in the ship's systems with her magic, she ends up transported to an alien world unlike anything she imagined: a box canyon in the middle of nowhere.

To get home, Twilight must enlist the help of the eccentric Red and Blue soldiers that live there... if she can get them to stop bickering first! Additionally, she finds herself being pursued by the enigmatic military agency known only as Project Freelancer. Back in Equestria, all is not well for Twilight's friends as forces involved with the crashed ship make themselves known. Reds, Blues and ponies will all have to work together to discover the mysterious connection between Equestria and Project Freelancer.

A crossover with Red vs Blue. Written with the intention for the story to be followable without having watched the series. (just don't expect to get all the references).

Now with editors! BradtheBrony and Rough_Draft.

I made a blog post explaining things. You should read it.

In the distant future of Equestria, Luna is recalled to Canterlot against her will to participate in a court case that will decide the future for sentient machines.

A dalek appears in Equestria - not just any dalek, but the one that had been corrupted by Rose Tyler's DNA. It has a choice of life as a pony, or dying, and finds that it cannot bear to die a second time. Thus begins a strange adventure as the dalek tries to find a place for itself in a world that is completely antithetical to its former existence and way of thinking...

...and why does that earth pony stallion look familiar...?

After being lost in time and space for centuries while fused with Discord, Twilight Sparkle has begun to lose her faith in herself and the Elements of Harmony. It is not until an encounter in Manehattan and a deadly fire that she begins to find her purpose again, and search for a way back home.

(Cancelled!)

Twilight Sparkle has walked the wastelands for a very long time, but now, at last, he has reached the end of his journey. He only hopes now that the gods will listen to his prayers, and finally allow him a good place to die.

(Please read the story before commenting on the description)

Banishing Queen Chrysalis was not without complications. Twilight has found herself on the plane of Innistrad, a dark place wrestling with ghosts, spirits, vampires, curses, and other things that should not be. Now she's on a world with no backup, no books and no plan beyond basic survival. Yet friendship is still a powerful thing, even in this new world of gothic horror. Now Twilight must find a way home, while still trying to do the right thing. [MLP:FiM][MtG:Innistrad block][Horror-genre themes]

During a climactic battle with King Sombra, Twilight Sparkle's Planeswalker spark ignites, flinging her far from home. Lost in a world she could never have imagined, will Twilight be able to overcome the many challenges she will undoubtedly face on her journey home?

A Magic: the Gathering crossover.
Colour is spelt with a 'u' because that's how I spell it, being British and all.
Post season three, not EQG compliant (because I haven't seen it yet).
Some light gore.

Celestia looked up at a sun that wasn’t hers, and for the first time in centuries knew fear.

Equestria is under siege and Celestia is nowhere to be found. Now it falls to Luna to hold the fractured nation together, while Twilight unravels the mystery of her mentor’s disappearance, and everypony prepares for war. Meanwhile Celestia, stranded on a foreign plane, must come to terms with the fact she may never see Equestria again.

A Magic: The Gathering crossover, though probably not like one you've read before. Explicitly written for those with zero knowledge of MTG.

FOME was especially helpful in his knoweldge of the MTG universe. If you like that kind of stuff (believe me, you do) check out his epic epic Elementals of Harmony.

And thanks to GhostOfHeraclitus for graciously allowing me to use his OC: Dotted Line. Dotted is the star of perhaps my favorite piece of fiction on the site: Whom The Princesses Would Destroy... which is a must read. (My story does not in any way shape or for reflect the universe of Ghost's Celestial Bureaucracy. If it did, it would have been a better story.)

Dark machinations are at work, and for Rarity, life has taken a turn for the worst. She's now in a place called Ancelstierre on another world, where nopony has ever seen or scarcely even heard of a unicorn before. What dangers lay in wait in this new land of strange magic and mystery? What happened to Rainbow Dash or Pinkie Pie? More importantly, how does she get back home?

Welcome to the Old Kingdom, my little ponies. Magic works quite differently here...
