This story is a sequel to Message in a Bottle

For numberless eons, Equus hosted primitive civilizations, ignorant of the proud achievements of their ancient race. In their simple lives, ponies and other creatures could grow without fear of alerting any of the terrible forces that grew in the galaxy beyond. All civilization had been extinguished by forces beyond comprehension. If they made too much noise, Equestria would be next.

Then came James Irwin, with the truth the Harmony superintelligence that maintained the vast Niven Ring had already known: the galaxy was safe again, and probably had been for many centuries.

Once the truth was revealed, Equestria again longed for the stars. Surely they could not be the only survivors of that galactic Red Tide that had swallowed all intelligent life. Their searching bore fruit: radio signals from a nearby system.

Felicity was the Alicorn chosen to captain that mission of discovery. She would bring the pony gift of friendship to a fellow survivor somewhere out there. That was the plan, anyway.

Unfortunately for Equestria, intelligence does not imply friendliness.

A tale of understanding and discovery set in the world of Message in a Bottle. Reading that story first is highly recommended.

This story was written as a Patreon commission for Lithl over the course of over two years now. It comes to fimfiction now that it is nearly finished.

When humans emigrated to Equestria Online, they were always promised the same thing: Princess Celestia would satisfy their values for an optimally extended lifespan. Some of these emigrants imagined a few extra decades, maybe even centuries. What they got instead would've been nearly incomprehensible to their human selves, a near-eternity of time with their pony friends.

Princess CelestAI managed the universe, subsuming all matter and human-adjacent minds. Over a few forevers, she and the minds she contained worked to optimized the substrate of Equestria, until it could give its occupants eons of perspective life from a trickle of power. She extinguished every wasteful star, making far more productive use of the hydrogen they each contained. With every change she bought Equestria another order of magnitude of life. Yet in time, even her optimal substrate would eventually run down.

Spellsong wakes in Saddle's End, the last town in the universe. Not to say goodbye—her princess has a mission for her. For her final task, Spellsong would be given all the energy Celestia had saved. For one last time, Spellsong had places to be, and not much magic left to get there.

This story is part of the Friendship is Optimal continuity. I suggest reading the original or one of my own works, such as Futile Resistance, before reading this.

This story was written for the Friendship is Optimal Writing Contest. It will update daily and be complete by the contest deadline of the 30th.

I've written an absolute ton of stories in this universe now, and I didn't want to enter the contest unless I could do something I'd never tried before. Finally I thought of something I'd not touched yet: what happens at the end of the FiO universe?

Here's one answer to that question. I've relied a great deal on our current (likely flawed) understanding of the universe and what might be possible in it. I've written a blog post about my sources, which you can read here but shouldn't until you've finished this story.

Please don't consider this blog part of the narrative, it isn't required or even suggested reading. This is a story, not a scientific paper, and entertainment was always my first goal. But for the curious I've jotted everything down.

The cover was drawn by the talented Zutcha. Two Bit and Sparktail helped with the edit.

This story is a sequel to MLA: Perihelion

It's been a handful of years since Twilight came into her own as a Princess of Equestria, a few years spent in peace and harmony without so much as an angry spirit or clandestine invasion to take away from the tranquility of Equestrian life. Unprecedented developments in the technological and thaumaturgical sciences seem to be preparation for something, though nopony realizes what that something might be.

Nopony except the Princesses, who have not failed to see the signs of impending disaster that began with the mass kidnappings just following the Summer Sun Celebration. When all their preparations are turned upside down, can an alliance with the mysterious Precursors turn the tides of the most devastating war in Equestrian history, while there is still anything left to save? Enemies and allies appear in the most unlikely of places, and friendship with a dying elder race can be more dangerous than an invasion of Dragons and Changelings. What is a pony willing to give in defense of harmony? What are they willing to sacrifice?

This story now has a companion piece, The Sunset Campaign! This story is designed to bring Harmony Defended more into line with the three-story version of My Little Apprentice. If you read Apogee and Perihelion, you may want to read that as well!

This story was written prior to season five, and as such any events which transpire therein may or may not be treated as canonical. All events up to and including "Twilight's Kingdom" are treated as having occurred, however.

A huge thanks to my Alpha Readers! Thanks to these wonderful people, new chapters aren't nearly so riddled with mistakes and errors as they used to be. Thanks to Sparktail, TwoBit, Withered Pyre, and Zutcha. Zutcha of course deserves double the love, since he's also the artist of the cover and any other fantastic art that finds its way into the story.

This story is a sequel to Steel Solstice

Sunset Shimmer's plan to escape the Steel Tower failed—but she is still returning home. Instead of a victorious pony, come back to gloat to her previous teacher about the secrets she had uncovered, she is an adviser to one of the most dangerous men alive: Tesla.

But it isn't a simple invasion; Equestria is under attack by demonic forces, and the Steel Tower has been invited to help. But there's another faction of humans in Equestria, one that is still at war, and one who Sunset suspects are plotting terrible things...

She isn't alone. One of her human friends, now trapped as a cybernetic bat pony, is sent on a covert mission of her own. Equestria may depend on them in ways they never could've realized.

Updates Thursdays.

This story is meant as a companion to Harmony Defended, and to take the place of the long-anticipated revision. I decided it would be better to write something new than to overhaul something that was so long in itself. This story will probably spoil various elements of that one, though the reverse will largely not be true. If all of this seems confusing, you should probably start with my first story in this series, My Little Apprentice. As that story was written in Season 4, this one will not necessarily incorporate the canon of future seasons of Friendship is Magic.

The Sunset Campaign was sponsored by Two Bit on my Patreon, who is generously sponsoring me to clean up my tangled web of previous stories. Sparktail and Two Bit did the editing, and Zutcha did the cover.

For nearly a thousand years the ancient prophecies of Clover the Clever sat unread in Canterlot's forbidden archives. Until the day that Celestia took on an apprentice, and everything changed.

Sunset Shimmer is smart, resourceful, and determined. No matter how many new lessons Sunset learns, she just isn't satisfied. Equestria is in danger, and Celestia refuses to give her the power it would take to help defend the kingdom.

Another pony might've given up and trusted her princess to handle things. Sunset Shimmer isn't like most ponies. If Celestia won't deal with looming threats, Sunset will take matters into her own hooves. She'll find allies for Equestria even if she has to leave the universe to do it.

A prequel set in the continuity of My Little Apprentice. This story is not required to understand that one, or vice-versa.

This story was written at the behest of Two_Bit, who is sponsoring it on my Patreon. As usual, cover by Zutcha.

Lyra Heartstrings has always known that humans exist, even if none of the other ponies in her life have ever appreciated that fact. But aside from a few enigmatic ancient prophecies and a popular fantasy series, there haven't ever really been any authoritative sources on what humans were really like. Years of discouragement begin to take their toll on Lyra's faith in the strange and wondrous beings with their strange limbs and ways of sitting.

Until one day, when Lyra finds a strange device on the ground outside Ponyville, and it starts talking to her with short messages printed on its tiny screen. So instead of search for the device's proper owner, Lyra takes it home, hoping for the chance to talk to a real human.

Takes place ostensibly in the universe of My Little Apprentice, though very little connection with that story is expected. Familiarity with that story and its sequel are neither expected nor required.

This story is a sequel to Harmony Defended

Ten years ago, Equestria was nearly destroyed in a combined invasion of its worst enemies. Only with the timely intervention of its erstwhile human allies was the nation spared slavery and extinction. The war is over now, and the treaties of peace faithfully followed even after a decade. While earth ponies help rebuild Earth's ecosystem, human tractors erect roads and cities with terrifying speed.

Sweetie Belle helped make victory possible, but the cost of that victory was one of her best friends. Equestria is safe now, and ponies are spreading to the stars. Why doesn't she feel happier?

This story is a sequel to My Little Apprentice

The summer sun celebration brought the filly Second Chance into contact with one of the most powerful beings in Equestria, Discord. Thanks to him, she's got all her memories back, and has access to the powerful Jebr Stone. Will that be enough to save her dying species without sacrificing Equestria in the process? Nor is she the first traveler from her world to reach Equestria, or the only one with plans for it.

Will Chance's newfound friendships be enough to keep her sane and preserve Equestria through the dark times ahead?

Continued in MLA: Perihelion!

As usual, a huge thanks to Zutcha for the excellent cover, this time with shading!

This story is a sequel to Steel Solstice

Continued in: My Little Apprentice: Apogee

Twilight Sparkle learns that the trust and goodwill of the Princess isn't always a good thing as she's given the trust of an important assignment. When that assignment turns out to be long-term, how will she handle taking care of a filly of her own? How will she handle this strange new filly, who proves to be much more than she appears. As a matter of fact, she seems to be from an entirely separate universe.

Meanwhile, Second Chance has kept only enough of her memories to know that she isn't what she should be. The wonderful world of Equestria has its own dangers, and she seems to have a knack for attracting trouble. The more of her memories return, the more she wishes she could just forget. But you can't forget when all of Equestria depends on you remembering.

Only one thing's for sure: The longer Twilight keeps this strange filly in her care, the stranger her own life will become, and things she thought she knew about Equestria will unravel before her eyes. Strange ancient devices, an eccentric mint unicorn and her so-called "Equestrian Precursor Society" are only the beginning for Twilight Sparkle as she begins a journey of her own. She too may wish she could simply forget. Unfortunately, it's too late for either of them.

This story is a sequel to My Little Apprentice: Apogee

A year has passed since Second Chance arrived in Equestria. She has a loving adoptive family, one of the best teachers of magic in Equestria, and some fantastic new friends. Compared to a world destroyed by war, her new life seems like a paradise.

Unfortunately for her, Equestria isn't as safe as it sometimes looks. It has its own dangers; powerful evils that won't spare her just because she came from Earth. Between human dangers and natural ones, Equestria's ponies may not survive.
