When Twilight and Applejack have a falling out over who can claim to have the best big brother, each will stop at nothing to prove theirs is better.

And their brothers will stop at nothing to make their sisters happy.

Once upon a time, in the magical land of Equestria...

One week ago, Twilight Sparkle was crowned the fourth Princess of Equestria. Tonight, Ponyville hosts the 1003rd Summer Sun Celebration, and Princess Celestia and Princess Luna want a vacation. With two fine young princesses like Cadance and Twilight to take over for them, nothing could possibly go wrong.

Celestia had a problem. Somepony wrote a novel about Nightmare Moon's rebellion. This made Luna quite unhappy, and unfortunately for her sister, Luna has not yet gotten the hang of modern traditions like freedom of speech, the abolition of the death penalty, and not bothering Princess Celestia when she's trying to sleep.

Fortunately, Celestia also had a faithful student, one who is now a Princess with an ill-defined portfolio and perfectly capable of dispensing justice by the laws of both today and one thousand years ago.

Now Twilight Sparkle has a problem.

It's been more than a thousand years since the Mane Six's adventures in Ponyville, and things look very different. Equestria is gone, devoured by chaos. Nightmare creatures roam the lands, changelings prey on the few remaining pony settlements, and all trace of the peace and harmony during Princess Celestia's reign has vanished.

Until, that is, a small group of ponies set out to map the Tangle, and find a slumbering dragon inside. Now Spike, a millenium out of his time and with only his memories to comfort him, is ponykind's only hope. Together, he and his new friends set out to find the one pony who can set things right: Twilight Sparkle.

AUTHOR'S NOTES

- Beware of spoilers in the comment section!
- Currently undergoing heavy revision for chapters nineteen and onward. The "lost" chapters - that is, the story as it was originally published - can be found here.

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.

Hundreds of years have passed since the wedding of Princess Cadence and Shining Armor. As with all mortal life, Shining Armor was fated to die and his soul to pass from the world. But with magic, his end was averted. What price will his immortality demand?

Now 100% approved by Twilight's Library!

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."

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”
