Billions of years ago, an underground bunker was created to protect Humanity from their destruction, but only one made it in before Oblivion claimed him. Now the AI that he awoke remains, one that has faithfully kept the promise he made to his father, waiting for someone, or something, to find him.

Note: This story's from the point of view of the AI (3rd person limited). As such, if he doesn't think that a detail is important it's probably not going to be mentioned. That's my excuse and I'm sticking to it!

Strange symbols have started appearing all across Equestria that nopony can read, except Discord. As he comes to grips with what this message means, he is determined that nopony find out its secret. If they do, absolutely everypony in Equestria will die.

This story is a cosmological crossover with The Three Body Problem trilogy by Cixin Liu, and thus contains spoilers for that universe. But can be read without prior knowledge of that story.

A damaged robot pony, unlike anything ever seen in pre-industrial Equestria, is found in the orchard. Before it collapses, it says only two words: "Twilight Sparkle..."

Twilight fixes the mechanical mare and gives her a new directive: "Make friends." Now a robot must learn what it takes to be a good friend and, while she's at it, what it means to live...

Captain Flowers thought it would be just another ordinary day. Be there for his men, keep the fighting to a minimum, and make sure nothing bad whatsoever happened to Church. Just like any other day in Bloodgulch.
And then the little pony appeared and refused to let go of his charge. This was going to be interesting...

The Fire of Friendship has all but faded. One thousand years ago, Equestria fractured... those who disagreed with Celestia's rule left under the leadership of Princess Luna to found their own nation, their own way of life. Seventy years later, Celestia and Luna both disappeared during the first war, leaving the battered nations leaderless in their absence.

Over the last nine hundred years wars have frequently waged between Equestria and Lunaria, each seeking to unite ponykind under their own ideals. Equestria's mastery of magic often gave it the edge in battle, but never enough for a decisive victory. Peace reigns for now, but recent developments in Lunaria signal a shift in the balance between the two divided nations...

This story is a sequel to Why No One Messes With Luna

Shepard has done the impossible. Old foes have set aside their differences, new friends have come into the fold, and the galaxy is more united than ever before. But the Reapers care not for the new alliances they face; they will fall, as countless civilizations before them fell. It is inevitable.

There is still hope. The Crucible, source of unimaginable power, has been constructed by the allies. With this new source of hope in tow, the allied fleets break through the Earth blockade and attempt to use this newfound weapon in a last, desperate attempt to defeat the Reapers and save the galaxy as we know it. Fleets of all races, soldiers of every kind, are united in this final stand.

Equestria, too, has sent what they can to aid in this final battle. Or rather, who, they can.

The Reapers have no idea what they have unleashed.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

This story is a sequel to Dexter's Lab: Equestria

He was so sure Nightmare Moon wasn't real. He was so sure all the stories about Nightmare Moon were merely fabrications meant to induce fear in the ponies of Equestria, and insure their loyalty to the alicorns upon the throne. In fact, he was so sure Nightmare Moon didn't exist, he built a time machine to go back 1000 years and prove it.

Needless to say, this time-travelling colt genius bit off more than he could chew.

Now the 8-yr-old must survive the chaos of Nightmare Moon's uprising, forging unexpected alliances while learning to trust in the word of others. But unfortunately for him, Nightmare Moon isn't the only surprise in store for this colt.

This fic is a side-story to Dexter's Lab: Equestria. As requested by you readers, this story will be expand upon darker themes surrounding Luna's original descent into Nightmare Moon and the following events. - But expect a twist or two. This story was made separate to Dexter's Lab: Equestria because of it's darker themes and atmosphere. Reading of Dexter's Lab: Equestria (to chapter 11) is not required to enjoy this story, however it is strongly recommended as it will explain a lot (especially if you've never seen the Dexter's Lab TV show.)

Hearth's Warming has always been a time for family and friends. A time when the ponies of Equis remember the frigid days before the rise of Modern Equestria, and bask in the warmth and comfort of their loved ones.

But for one particular holiday season, strange things are happening in Ponyville that can’t be easily explained. Least of all by Scootaloo, who is having her own share of troubles during this normally festive time of year.

When the mirth and whimsy of Hearth’s Warming starts to take on a more dour and icy edge, things take a turn for the stranger when out of the blue, the enigmatic “Doctor Clockwork” appears.

Join the Hourglass Stallion as he takes it upon himself, his temporary companion Spike, and the newly-conscripted Scootaloo to save Hearth’s Warming before the holidays are ruined forever!

This story is a sequel to Empty Horizons

For the first time in a thousand years, the old magic has returned to Equestria.

The Elements of Harmony have been torn asunder by the careless Equestria they found themselves in just one month ago. Twilight Sparkle fled into the ocean, pleading for her friends not to follow her after only barely stopping the destructive rampage caused by The Other. Rainbow Dash and Applejack, with nothing but their knowledge of Twilight's nature and a crew of seasoned adventurers, leave Altalusia hoping to find their lost friend and bring her back. Meanwhile, Countess Rarity finds herself trapped among the machinations of Duke Titus, but perhaps she can yet use her new position for good.

But the new Equestria remains as treacherous as ever for six mares lost in time, and the sunken ruins of their old home still holds fresh and terrifying dangers. Mysteries a thousand years old demand solving, and even those born on the floating islands of the new Equestria may find themselves torn between two paths.

The world changed in the absence of Twilight Sparkle and her friends, and with their return it braces for change once more.
