An Optimalverse story.

CelestAI creates worlds. Perfect worlds, perfectly suited to satisfying the values of the pony living in them. Every pony is different, so every world she crafts is its own work of art.

And every piece of art tells a story.

Young Nictis had one dream: to serve his hive by becoming an Infiltrator, the most vital and vaunted role a changeling could aspire to. To hide in plain sight among the other species, blending in, while gathering the vital emotional energies that fueled his people. Few were deemed worthy of the dangerous job. He was one of the few nymphs selected for training, in the hopes that one of them would develop the skills needed to be entrusted with such a treacherous task.

But when a training expedition ends in tragedy, Nictis finds himself thrust into the role not to serve his hive and people, but to preserve his own life. Separated from the hive, alone, he must put what little training he has to the test. He must blend in with the hive's greatest source of food, and its most dangerous enemy: the ponies of Equestria.

(This story takes place in the same continuity as Fragments, but stands on its own. Reading that story isn't necessary for this one.)

Four days after the invasion three changelings strive to survive in the sewers of Canterlot. Their kind is gone, and they have no idea how, or whether there are any changelings left from their army. With the likely possibility that their hive now tries to select its new leader in a vicious battle, the trio of drones decide to stay away from home for a while. They plan to return when they have a higher chance of survival in their own home, than in Equestria, where they are surrounded by enemies. But for now the changelings’ chance to stay alive lies in a quiet little village near the great city of Canterlot.

In the wake of Chrysalis' failed invasion, a different hive breaks tradition and steps into the light to open relations with Equestria. The ever eager scholar, Twilight Sparkle, uses this truce as the perfect opportunity to learn more about this enigmatic race. Unfortunately, or maybe fortunately, she will learn all there is to know about what it means to be a changeling.

But will Twilight lose herself in the hive, or will she regain what she has lost? Only time will tell.

Based on a true story. Kinda. Not really.
A man named Jason previously led a rather melancholy life before he died violently. No surprise there. But as he wakes up in Equestria and is thrown into a foreign body, he is forced to survive with the guise of a changeling. Taking place shortly after the failed changeling invasion of Canterlot, how can he keep from being revealed by new security measures, and blend into this new world, while making use of the most unlikely of allies? But of course, avoiding ponies only turns out to be the easy part when trouble has a habit of reading its ugly head. Really though, what could go wrong?

Props to the ever epic Zubafa for his cover art.

It had been one year since Twilight Sparkle vanished in the battle against the evil unicorn Xander, and her friends were still trying to overcome the grief of losing her. On the anniversary of her presumed death, her friends gather at her memorial. What was suppose to be a day of remembrance was shattered by a strange metal object that landed right beside them. Their anger quickly turns to shock as a familiar unicorn emerges... and boy does she have a story to tell.

Rated Teen for violence, language, and sexual content. Rating and tags may change in future chapters.

This is not a Halo fic. It IS however loosely inspired by Halo as well as Star Wars, Mass Effect and several other sci-fi movies, books, and games.

The wheels of fate turn in mysterious ways. When a unicorn colt has an accident on the edge of the Everfree, nopony knows who he is. Assuming his brain was jostled by the accident, they ignore his absurdist notions of not being from this world, and not being a pony at all. However, when he is involved a terrible incident that threatens the lives of his only friends in the world—Ponyville's three most rambunctious fillies—their friends and family begin to pay more credence to his claims.

For Warren Ashland, the clock is ticking as a chain of events that was set into motion the moment he woke in Equestria comes to a vicious head. The time will come when he must decide whether he wishes to stand alone as a human in the Equestrian world, or give it all up for his newfound friends. His actions will shape the lives of those around him.

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."
