Decides that she's going to say buck it, and finish up some old spell of her own. By violating magic, physics, and nature. Twilight and the Mane 6 truly discover a new form of magic, and the power of friendship. Much to the consternation of Celestia and amusement of Luna.

The Yaks, a great and noble...er...people that are full of pride and demand only the best...for themselves.

And when they don't get it, they scream and shout, and smash stuff.

This is the story, of what happened when they went too far, and messed with a purple pretty pony princess so much, even she didn't want their friendship.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Suddenly finding herself in hell, Twilight is presented with one fact: for the rest of eternity, she's stuck in a library holding every book possible. She's expected to organize them and is allowed to read them.

What makes this hell, again?

Now has two Spanish translations, one by SPANIARD KIWI and another by Pugg-Senpai.

Twilight Sparkle never was a Unicorn and she didn't even know it.
What happens when her true heritage comes to light? Will she willingly embrace it? Or will she be forced to?

Beware of spoilers in the comments!

In quite a few of my favorite stories on this site, I've seen that the 'plot/conspiracy to overthrow Celestia' pltline utilized, either as the primary threat or just something in the background. I decided to do my own take on it, taking a page out of "Winning, and the pitfalls therein" by RandomPC, found here

Just because the two sisters have led Equestria through thousands of years of peace doesn't mean there aren't those who think they can do better.

With a powerful artifact on their side, a group of rebels has sealed Celestia in her palace and stripped her of the majority of her powers. As the last of her guards fall, she hears the pounding on the throne room doors and knows the end is coming soon...

**Featured on the front page on 8/12/15; both surprising and flattering seeing as how this is the first thing of substantial length I've posted here. Thanks all!

**Now with a dramatic reading!

Princess Ember is not the biggest, strongest, or meanest dragon out there. In fact, she ranks pretty low in all three categories. Despite these disadvantages, she managed to pass her father's trials and become the Dragon Lord. Only one question remains: Now what?

While Friendship helped her win the day, it failed to give her a run-down of the intricacies of draconic politics, or lack thereof. Lucky for her, her father Torch is here to guide her down the path of a true leader. Soon, dragons across the world will be spreading the magic of friendship the best way they know how.

With fire.

'Other' tag for Torch, Ember, and a few cameos. Properly tagged with the update. Still needs a 'Stupid' tag though.

Princess Twilight Sparkle discovers a fact about alicorn reproduction she never expected.

So do the other princesses.

Now on Equestria Daily. Those cruel, cruel people.
And a wonderful reading by Pony and Wolf Productions

Scootaloo wants to be just like Rainbow Dash, and barring that, to be like every other pony. She's ashamed of her true nature, the one she must hide from everypony or be hated and cast out, or worse. She doesn't know what she is, only that she can't eat the same way other ponies do, and she has to keep the terrible consequences when she feeds too much always hidden and never seen. But when a pony begins to truly care about her well-being, Scootaloo finds out that being loved makes it harder to keep a secret than when nopony cares about you at all.
