Rarity has been working awfully hard lately so Twilight Sparkle, being the good friend she is, goes to check up on her.

Should be golden now.
Now with a reading!

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Of course, learning from Discord was never going to be simple. And after a while, being a draconequus doesn't seem so bad anyway....

For Sunset Shimmer, letting a group of impressionable high school students in the know about another dimension where magic reigns and talking ponies are the norm is not the easiest thing to handle. It does not help that the portal to this dimension is right in front of the school.

Sooner or later, though, she has to deal with more than mere questions about Equestria. Twilight becomes curious enough that words won't cut it for her anymore. She wants to see this dimension for herself.

So, Sunset begins by offering to bring her camera through the portal to take pictures and videos of her next trip there in Equestria.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

It has been twelve years since Twilight Sparkle was shrunk to 1/100 of her original mass to minimize the damage caused by her uncontrollable surges. Twelve years of struggles, challenges and hard work as Princess Celestia’s student, in which the tiny mare found the joy and excitement of facing everyday adventures of a huge world.

One year before Nightmare Moon’s return, Princess Celestia sends her tiny student to learn about pegasus magic from professionals, the Wonderbolts themselves. Much to the princess’s pleasant surprise, Twilight forms strong bonds of friendship during her one month of studies with Soarin' and Spitfire while the Captain of the Wonderbolts, Impressed by Twilight’s talent in magical surgery after the crystal mountain incident, offer her a job as one of the Wonderbolts’ medics.

While Twilight accepts the offer with Celestia’s blessing, provided that it would not last longer than half a year, the other Wonderbolts are not too happy with this idea. Will Twilight manage to win their trust, and what kind of adventures and challenges await her so far away from her home in Canterlot castle? Only time will tell.

This is a sidestory that takes place in "Celestia's Tiny Student" between chapter 20 - "Camping Trip" and chapter 21 - "Birthday Party."

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.

All of Equestria is united in celebration for the return of their beloved Princess Nightmare Moon. But when Celestia and everypony else recieve her she's skeletally starved, filthy, and very nearly dead. Meanwhile, while everypony's eye is turned, a lusty Blueblood pursues Twilight Sparkle, intent on adding her bloodline to his own so his family might step closer to godhood. (Alternate Universe, there never was a Princess Luna)

Batman has defeated many foes in his life. The Joker, Two Face, The Riddler, Poison Ivy...just to name a few. However, no matter how hard he tries, there was one foe he could never defeat...Time.

Finally beaten, he admits defeat, ready to give up...

But a tiny white unicorn might have something to say about that. A single word that gives him hope. A legacy. A way for Batman to conquer time itself, even if Bruce Wayne cannot.

That word...is "Father".

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

(Sequel to Stardust, which I recommend reading before starting this. Fortitude Amicitia and Broken aren't required reading but are supplemental to the storyline)
(Gore tag for blood and violence)
(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)

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."
