"The arrogance of our kind is thinking nature is in our control, and not the other way around." ~Serizawa

When a foreign country far to the east, long since isolated from the rest of the world, reaches out to Equestria with a desperate plea for help, It’s up to Twilight and friends to save the day.
Yet things will be far from simple. They will find themselves thrust into a strange new land under siege by a terrible foe, pitting them in a race against time to stop a titanic force of nature before it crushes them all in its relentless path of destruction.

Ripped from home with no explanation to a place that is both incredibly strange and eerily familiar. What world he walks on, what these creatures are, why he's here. There are many things Rajrishi does not understand about Equestria. He hopes to fix that.

But mostly he just wants to go home.

A Human turned pony hybrid finds himself in Equestria, when he sees what Discord's doing to the world he realises that the world is now like a cartoon. Taking that logic a step further, if the 'Normal' rules of Magic and Science don't apply, then could anyone shape the world to their Will, seeing as the rules that would normally stop them aren't working.

After a quick experiment, the Human seeks the assistance of the one pony with experience in shaping the fabric of reality, Princess Luna.

Together they conspire to derail Discord's plans.

Twilight Sparkle was granted a Royal Library as part of the castle in which she is residing, as Princess of Friendship. If her old library was good for the small village of Ponyville, the new library is graced with numerous and highly priced and valuable books, both great and small.

Pinkie Pie found joy in the value hidden within the still small library from the first day. She is regularly coming back, in search of books of direct interest, or randomly going through the books before her.

Pinkie Pie is found incapable of forgetting even the smallest detail, and having direct access to the wealth of knowledge she has been gathering: even if she had managed to forget her very own birthday, or other details of no humorous value.

As a Princess, Twilight Sparkle is holding on to books of value, books of great power in magic hidden among them. What happens, when the pink mare stumbles upon the dangerous material contained within these ancient tomes?

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Anon likes his life to be simple. He wakes up, goes to work and sometimes gets himself a good book to read while he is home. It's a routine that he likes to follow, it makes him feel like he has a bit of normality with his life in Equestria. The fact that having Celestia come crashing into his home as part of his routine should prove that his life is anything but normal.

Ace was a street magician with a lucky streak. His luck was legendary among casino owners and fellow magicians. Any risky trick would succeed flawlessly and any gamble would pay off for him.

After performing his greatest and final trick he is brought face to face with the entity responsible for his incredible luck. The goddess of fortune herself. Lady Luck.

She offers him a deal. To become her champion, her Wild Card, and go to Equestria to spread luck among those who need it the most. So he finds himself in a magical land, in a new form, and ready for anything that comes at him. To a reasonable degree.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!
