For the longest time, Epona has served as the loyal mount of Link, hero of Hyrule. But one day, she finds out that she's actually from a world inhabited by intelligent, colorful equines. And not only that: Her daughter is one of the six main heroes from that world. But that is only the beginning.

When the worlds of Equestria and Hyrule get into contact after a millennium, lots of hidden conspiracies are revealed. Evil fiends from a time long forgotten emerge and some ponies begin to understand their powers as sages. But the one important question will be: What will Epona choose? Her friends from Hyrule? Or her family from Equestria?

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.

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

(Sequel to Stardust, familiarity with this is recommended!)
(Proofread by Arzoo!)
(Coverart commission drawn by the amazing KairaAnix!)
(Crossover with XCOM: Enemy Within, though the crossover and human elements are minimal)
(Featured 4/28/2014, thanks folks!)

Discord has a problem. He has a tendency to not think through his actions all that well, poor impulse control, and no ability to figure out how others will feel about what he does. Even with a friend helping him, sooner or later he's going to do something that'll get him stoned or hit with a reforming spell or whatnot. So what's he to do? Ask the smartest pony in Equestria for a solution, of course!

He probably wasn't expecting to get "Have Celestia let you rule Equestria again" for a response.

No one else was probably expecting to enjoy it.

When Trixie's brand new wagon breaks down in the middle of Hoofington, she finds herself unable to repair her broken wheel herself. So she decides to call upon Equestrian Roadside Assistance for help.

It will be a decision she is doomed to regret as she is forced to confront automatic voice directories, unhelpful operators, intolerable hold times, lovecraftian madness, gastrointestinal distress, and moronic protocol.

Trixie will never leave Hoofington with her sanity intact.

It's been a rough day for Twilight Sparkle. She was awoken in the middle of the night to save the town, had a chance to study an alien artifact ripped out from under her, and is now stuck with Applejack, Fluttershy, and her arch-nemesis Queen Chrysalis in some alien fighting tournament with a bunch of... things she doesn't even want to try and start describing without a cup of coffee and some asprin!

Indeed, Twilight and her friends have been summoned to join the latest Smash Brothers tournament! And as they explore the mysterious 'Smashworld' and meet new, colorful characters, they will be pitted head to head against new friends and enemies as well as each other! Can their friendships survive being forced to fight one another? Why are all the other 'smashers' so on edge? And what's with the bizarre being that purports to be the creator of this world, "the Master Hand?"

Only one thing is for sure. It's going to be a doozy.

Applebloom just wanted to spend a day with her friends, crusading for her cutie mark. Instead, she found something even deeper and more troubling about herself. Turns out she's not even a member of the Apple Family by blood. In fact, she's not even truly native to Equestria! She's an alien! An alien robot no less!

Now Applebloom will have to deal with the reality of her origins and try to cope with them and her newfound abilities as she moves towards her future; a future that just might never come to be if her new foes have anything to say about it. Decepticons are, after all, a monstrous cabal.

Now, it's up to Applebloom to light Equestria's darkest hour.

Equestria is barely three years old, and already danger threatens the fragile peace forged between the pony tribes. Monsters stream out of the Forest Ever Free on a daily basis, and now a prophetic dream foretells of even greater chaos that will befall the land.

It's up to Star Swirl the Bearded and his team of manly, heroic, eminently bearded (and strangely familiar!) stallions to brave the dark and murky Forest Ever Free in search of their one hope for salvation. Along the way, they'll learn more about the history of the land they've claimed as their own, not to mention each other. But as their unintended friendships grow, the forest will try its best to drive them apart.

Can they withstand the epic trials before them? Can they save Equestria? Will Star Swirl be known forevermore as the creator of Equestria's first beard-restoring spell? Journey a thousand years into the past and discover Equestria's epicest, beardiest history lesson ever!

Gordon Freemane is a pony who never got the memo about the Harmony that binds all of Equestria together. Or perhaps he's more in tune with the Elements of Disharmony, if there is such a thing. Whatever the case, he's as happy as can be when he's left on his own to do whatever he wants, which usually means avoiding the world around him and making plans for getting rich. It's a good thing he has a very bright mind. A very bright and active mind that helps as much as hinders him on his journeys to find the two things he loves: peace and bits.

In this firsthoof account, Dr. Freemane tells us about the places he's been, the things he did and the ponies that got in his way.
