It is a known fact that different universes have different time constants; that is, while one universe may experience a second, a different one might experience two. This causes a very large temporal drift between universes where, more often than not, the season doesn't even match up, let alone the day. However, in this holiday season, everyone's holidays are lining up perfectly. The Emperor of Mankind wants in on this.

Join the ponies, humans, daemons, and other creatures for a look at many different expressions of the holiday spirit.

Part of the Songs of the Spheres continuity - a Christmas/Holiday special! Takes place after chapter 073 - The Hunger for Games.

-GM, master of Nirvana.

Twilight Sparkle of the human world has created the first ever Artificial Intelligence program that can learn and further evolve. She has also uploaded that program into an already highly advanced robot, creating the perfect protector of peace. However, things eventually go awry as the AI's view of protecting the peace clashes with that of Twilight and her friends. Now, they must race against time and save every organic being on the planet from the rage of ULTRON.

1) Ultron is a Marvel Comics character created by the writer Roy Thomas and the artist John Buscema, and is owned by Disney.
2) The story takes place between Forgotten Friendship and Rollercoaster of Friendship.

Abstract: Humans and Ponies, by our very nature, are social creatures. We gather, we find partners, and we form families. This is no less true for members of the Foundation than it is for any other group. Unfortunately, due to the nature of our work, such relationships create the potentials for massive breaches of security, and in several cases, have required the use of amnestics. By granting the loved ones of specific Foundation personnel a special class of Level 0 clearance, not only does one decrease what could be considered a potential security breach, but also reduces amnestic use, and in many cases, helps alleviate the stress and physical/mental strain constant deception of loved ones has upon Foundation personnel…

Twilight has been working for the Foundation for several years now, ever since she rose to become Celestia's personal student and turned 18, she has been working with the Foundation.
But now, after all the adventures she and her friends and family and gone through, all the tears and laughs, they still do not know of her affliction with the Foundation, or that the Foundation even existed.

After witnessing how Dr. Deep Study's daughter denounced her father as a workaholic who never pays attention to her and loves working more than her, even though he died preventing a ZK-End-of-Reality Scenario, Twilight has decided it was time to activate FD90, and reveal to her freinds and family...what she does in the dark.

Muffins at the End of the Universe IV

For many months Twilight Sparkle has pondered her role in the universe, while marooned in a crashed pod in the far future, eating reprocessed food and counting floor tiles to occupy her mind. Then she discovers a loophole in Equestrian colonial law, allowing her to rule over her new domain as princess, much to the annoyance of her colony's three citizens, Trixie, Derpy and Doctor Whooves.

As Twilight goes mad with power, treachery and revolution are in the air, as well as some explosive chemicals thanks to the Doctor, culminating in a finale of political intrigue involving a bubble wand and a rather dubious stick of celery.

This story is a sequel to Convergence

Equestria was just a game, one of an endless number of semi-illicit online games created to take advantage of the ubiquity of cheap augmented reality hardware. But that changed, when for no reason anyone knows, the virtual population of Equestria woke up.

Two decades have gone by since then, and the world has been transformed. The former game network has grown to encompass the backbone of trade, infrastructure, and research the western world over. Its vast computational resources have given rise to an infinitely subdivided world of overlays and sublayers, coterminous with the various cities and towns within Equestria. Every person in the modern world is assigned a Synth, a pony personal assistant that adapts to their needs and helps them access those parts of the world governed by Equestria's systems.

It is a world Dakota barely remembers, thanks to an automobile accident that turned most of her body to mush. But thanks to the medical miracles created by joint equestrian-human research, her life is saved by a remarkably new series of implants.

But Dakota isn't content to sit around while her body slowly knits itself together. There are unanswered questions to answer, questions that will ultimately lead her to the oldest mystery of both worlds.

For months, the Dovahkiin has chased Alduin. When he finally confronts him, Alduin barely escapes.

By running from his fate, he merely sealed it.

No creature runs from an Orc.

Human kind was dying from its now toxic atmosphere that was full of a new chemical that poisoned them to no end. This new chemical allowed for the wildlife to evolve at a rapid pace allowing them to cope with their new environment while also making some sentient with new powers that could only be described as magical. Now the leading government plans to use this chemical and its mutations to escape their dying world to what they believe to be paradise.

They just have to take it first from both the nations of the planet and the experiments who have tasted what freedom truly is. Join this rag tag resistance as they do they're best to defend this peaceful, non-threatening world from their former slavers.

Act One, A Whole New World!

Act Two, War of the Worlds

Act Three, All That Remains

The Doctor is on the run, from an adversary that has pursued her across all of space and time... the last enemy there can ever be. Fortunately she has family and some good friends along to help!

A crossover based on Jodie Whittaker's Doctor. Also explores the question: what if Time Turner wasn't the Doctor all along?

Poor Twilight Sparkle: pride and joy of the University of Eohippus, she is in charge of a team of the most brilliant unicorn minds (plus Fluttershy) of her generation. So it's a shame they're also at least six kinds of deranged and ten kinds of embarrassing.

There's Twinkleshine, whose girly-girl demeanour masks an ambitious monster. There's Moondancer, who's about as social as an oyster, and Lemon Hearts, who's about as charming too. There's Lyra Heartstrings, whose research barely qualifies as sense, never mind as science. And then there's Sweetie Belle, who should totally be in school but who'd much rather hone her skills as the world's worst personal assistant secretary fangirl... thingy.

However, this is merely the start of Twilight's problems. In the midst of mad science and a city overstocked with adventure, she'll confront MIA mages, enigmatic infernos, freaky furniture, political plots, hush-hush histories, and worst of all... the fact that she is destined to solve everything.

Oh, and Trixie's in there somewhere.

It's totally gonna go wrong.

On a rather boring day, Discord lounges about while in his chaotic realm. But without warning, a large amount of bio-mechanical warships, armored soldiers, and alien robots start breaking into the realm, beginning to take siege of his home and tunneling their way into Equestria. What follows is why they shouldn't be messing with the Spirit of Chaos.
