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.

You know that feeling? You know, the feeling that you get when you realize you've forgotten something that is very, very important? It is 10:32 p.m. on Hearth's Warming Eve, and Twilight Sparkle has just gotten that feeling...

"All my life, I've wanted to fly
But I don't have the wings, and I wonder why
I can't break away..."
Most pegasi figure out flying easily enough. Heck, most of them figure out how to do it before they even get their cutie marks.

But not me. I couldn’t do it, no matter how hard I tried. I couldn’t even hover. Not for more than a few seconds, anyway. And not even Rainbow Dash, the greatest flier in Equestria, could seem to help me. We tried everything, and I failed every time. Day after day, I tried – and day after day, I failed, until finally I was ready to just give up. I’d never be able to do it. Nopony would ever be able to help me to fly...

...until one day, somepony did.

Edit: Now a collaborative effort with Loyal2Luna

Commander Shepard has been through a lot, but now that the Reaper War's over he can finally relax and take a little R&R, right? Soak up the sun, grab a few drinks, spend some quality time with Tali, introduce a new race to the galaxy... wait, what?

In the aftermath of the war, a new species has been discovered amidst the destruction and fire. A species that have access to powers never seen before, powers which could prove vital to the continuation of galactic survival.

The Citadel Council has elected to send Shepard, along with the rest of the crew of the Normandy, to introduce Equestria to the universe outside of their solar system.

Now Shepard must wade through obstructive bureaucrats, antagonistic journalists, and the odd, angry prince in order to bring Equestria into a new age of space and adventure.

So settle in, it's going to be one hell of a vacation!

Now has it's own TvTropes page

A thousand of years of life experience would no doubt teach Princess Celestia much about romantic relationships, and that is exactly what Twilight wishes to learn from her beloved mentor. When Princess Luna catches wind of these lessons, however, she sees a chance to relight the fires of love within her sister again. But when a “one-time fling” turns into a life-long infatuation, Luna and a reluctant Cadance must race to reverse the effects of their meddling before Twilight finds herself in a most compromising position!

But can she truly resist the total affection of a goddess?

Looking back, it should have been obvious. It wasn't at the time of course and they knew that, but it was now. All those brief moments they spent together, the close encounters, it was like they were dancing around the subject.
And it all began with something so very small.

Set during season two.

Edit: Yes, I won the contest, to my absolute glee!

"Twilight isn't exactly a social pony." Could win me the Understatement of the Year award.

However, what most ponies don't know is that Octavia, a high-class socialite, isn't exactly much better herself, despite countless rumours about a liason between her and a certain DJ.

Now, drawn back to the upper-classes that she tried so desperately to get away from, can Twilight Sparkle find solace, and companionship, from one of the very socialite ponies of her past that she is so desperate to escape?

The TwiDash Project is a series of vignettes and short stories depicting the budding romance between Twilight Sparkle and Rainbow Dash behind the scenes of season two and onward, taking place during, before, and/or shortly after canon episodes.

Concept is based on the The AppleDash Project by bookplayer. Bookplayer has kindly given her blessing for others to explore the idea with different ships.

Editing by Formerly Committed.

The TwiDash Project is co-authored by bats and Subsolar Drift. Authors of different chapters will be indicated in the chapter title.

In 2185, during his campaign against the Collectors, Commander Shepard discovered a previously unknown species whose origins predated any other race in the modern galaxy. Following a daring rescue from their ancient sanctuary, the Equestrian Herd was brought back into the galaxy where, for the first time in eons, they must walk their own path.

Knowing full well the terrible threat that lingers on the edge of the galaxy, the leader of this newly freed race fights to secure her people’s future while attempting to prepare for the storm on the horizon.

This is her story.

The long awaited Sequel to Mass Effect 2: The Equestrian Equation This is a reader directed story. Your choices will shape events.
If you favorite, also like! It's one little button click that makes all the difference.

Also, this series has its own TVTropes page now! (Special thanks to user CrowMagnon for setting it up).

Twilight takes a walk in the woods near Canterlot to clear her mind, when a mischievous little phoenix starts dropping chestnut shells on her head. Quite a familiar mischievous little phoenix.

Somewhat inspired by the song "Evermore" by Alison Krauss, a story to perhaps make its reader smile.
