Equestria finds itself caught in the cold war between the United Federation of Planets and the Klingon Empire. Can friendship prevail, or will this cold war turn hot, despite their best efforts?

This is a crossover with Star Trek, taking place in late 2269 of the Prime timeline, during the fourth year of the five-year mission of the original television series. It's not a crossover with the movies made by J.J. Abrams. It is mid-season five or so for Friendship is Magic. it is my humble offering for the fiftieth anniversary of Star Trek, which debuted September 8, 1966.

Thanks to FoalsHalf for being essentially my co-writer/sounding board, and to all those who have helped with proofreading and editing.

A first-in scout from the Associated Worlds investigates the anomalous star system IGS 254672, expecting to find the home of a machine god. She finds herself making first contact with sophont ponies instead. A couple of them are weakly godlike ponies, but still...

Neither world will be quite the same again.

(This is actually a crossover with the original SF that I write as my day job, which is to say with the universe of Vignettes of the Star Empire and The Core War and Other Stories, and if you like - although it should not be necessary to read this - you can read a whole selection of the nanofiction I write in that setting over at the Eldraeverse blog. I also have a Patreon which exists to fund my ongoing original writing, but if anyone wants to give me money for this instead - I'm not asking, in this case, but you never know - I surely won't turn it down.

The Eldraeverse also has a Discord, which has an #advancedverse channel specifically for this fic's AU; feel free to drop in at: https://discord.gg/SnzkKhf

As such, I should warn you in advance, gentle reader, that updates may be erratic, because I also have said writing-as-a-day-job to do and it has to take priority. I hope that won't put you off.

Timeframe-wise, it's safe to assume these events start sometime in the middle of S3, and continue from there. The situation will of course butterfly-effect away from canon with reasonable speed, and there may be a few changes needed in the course of the fusion, hence the AU tag.)

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."

This story is a sequel to A Stitch in Time

Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.

Now with a Tvtropes page!

Princess Celestia: Goddess of the Sun, ruler of Equestria, beloved Princess of ponies. She is loved by all, and loves all in return. A calm and wise ruler, she sits on the throne in Canterlot, maintaining peace and harmony throughout the land.

What most don't know is that her past is much darker: She was once a commander of legions, a warrior and scientist of unmatched skill. Thousands of monsters and abominations fell to her forces, slain in the name of an old leader, one entombed within his own throne. Free of her old form, free of the powers of Chaos, she was cast into a new realm, in a new form, with a new lease on life.

She is the God Emperor, Eternal Ruler of Equestria and Lord of the Imperium of Man.

As they learn the secrets of their shared past, it leads to revelations about their friendship, families, and their long sought after talents. What they discover and accomplish along the way is beyond what anypony would have thought possible.

There is now a sequel! Three Wishes: The Hole In The Sun

And a (more or less) standalone Christmas Special set between this and the sequel. Cinder Claws: The Caribou Legend Of Kol-Klor

Big thanks to totallynotabrony, Dusk Watch, AugieDog, and Piquo Pie for prereading and editing help!

The discovery of a tiny extraterrestrial object within our own solar system makes a strangely equine alien race aware that the Earth is inhabited by an intelligent species, and they're on their way to come visit.

But since space is a really, really, really big place, they aren't going to get here for about a thousand years. They do have FTL communication, though, so while we wait maybe we'd like to be pen pals...

Twilight Sparkle is aware that the manipulation of matter at the sub-atomic level is a potential source of enormous amounts of free energy. She also knows that this is extremely dangerous, and that these spells are only for the highest level unicorns. She is therefore somewhat concerned to discover that Pinkie Pie has found another way to do this, with a curious contraption in the basement of Sugarcube Corner.
