There are 100 billion stars in the Milky Way, and humanity is determined to explore every one. We send probes, probes with the blueprints to reproduce human explorers upon arrival. Uninhabited worlds the galaxy over can be colonized and populated, until after many years they too can join the vast throng of interstellar civilization. But if a probe is very, very lucky, it will land on a populated world instead. Equestria is one such world.

Even so, it's far from perfect for colonization, not with an environment lethal to human life. But each probe is resourceful and armed with the greatest machine intelligence mankind has devised. If placing a human mind into a newly manufactured human body won't work, it will just have to get a little more creative.

This story was written at the behest of Canary In The Coal Mine, who is sponsoring it on my Patreon. As usual, cover by Zutcha. Editing by Two Bit and Sparktail.

Fantastic prereading help from: Chyre, Danger Noodle, Doctor Disco, and Doggyshakespeare (who also did the Esperanto translation). Thank you all for helping to make this story more readable and more consistent for everyone.

Twilight Sparkle's long journey had been aimless. Formless. A search for something she could not, or would not name. Her living, singing ship had plied the void for so long with no destination in sight.

But everything is different now. This is a mission of mercy.

Thank you to TheMaskedFerret for her help, and for being a friend when I needed one. And for ScarletWeather, who also read this and is also very good.

This story is a sequel to The God Empress of Ponykind

A message rings through the Warp: "The Game is broken, only Destruction remains". Celestia hears it, fearing for the lives of her former subjects and those of her beloved ponies. Unwilling to sit idle, she has chosen a dangerous path: return to the Imperium, take up the mantle of Emperor of Mankind, defeat the coming storm, and save Mankind once and for all.

With Twilight Sparkle to aid her, Celestia faces new challenges and new enemies. Her forces are scattered, her people assaulted, and the enemies of Man grow stronger with each passing day.

The Time of Heroes is gone. Now comes the Time of Ending.

Sequel to God Empress of Ponykind. Reading that first is strongly recommended.
Rated T for 40K related violence, but that might change at some point.
Comments contain spoilers. You have been warned.

Principal Celestia has accidentally fallen through the mirror into Equestria, and it may be a bit before she can go home. Until then, she has to learn to cope with a strange world, in a strange body.

At the same time, Twilight has to figure out how she can help her new guest while keeping Equestria from freaking out over the presence of a second Celestia, and Sunset Shimmer has to figure out how she is going to make amends with those she had left behind in Equestria, while keeping an eye on her Principal.

Disclaimer: Since I wrote this description ages ago before I even knew the plot, the story is mostly pure comedy in the beginning, with eventual Sunlight and Chryslestia shipping!

This story is a sequel to Iron Hearts: Book 5 - Suffer Not the Alien to Live

An Age of Iron story.

Months have passed since the destruction of the Ork Space Hulk and the end of the war against the Waaagh that threatened to swallow the Centaur system and all its inhabitants.
The Iron Warriors' 38th Company is the absolute military power on the planet, and the survivors of the Lamman Sept and the ponies of Equestria stand with this mighty army of Chaos as they claim Centaur III as their own. Although the other nations of their world may not fully recognize the Company's dominance, it is no matter; the Iron Warriors make plans to return their cargo to the Eye of Terror and return to their eternal trade of piracy. The planet is secure, and can be shrouded by Warp storms at their whim. The natives are divided, weak, and anyway occupied fighting off the scattered Ork warbands. The military supremacy of Chaos is unchallenged, and bolstered by Equestria's reluctant, but hard-earned support.
As Ferrous Dominus expands its operations and the fleet performs its long-suffered duty, it seems nothing can stop the Iron Warriors and their equine allies. The denizens of this conflicted world start to hope that at last peace - if not a distinctly unstable and militaristic peace - has come, and they might start constructing a new, better future from the ruins of war.
But hope... is the first step on the road to disappointment.

This story is a sequel to The God Empress of Ponykind

One thousand years ago, Luna, Warmistress of Equestria and sister of Empress Celestia, fell to the powers of Chaos and plunged Equestria into a brutal civil war. The Traitors were defeated, but not before Luna made the ultimate sacrifice and was sealed away in the Immaterium with only the soul of a slain Primarch to keep her company. For a millennium she has been locked away, waiting for a chance to return to her home and her sister.

Now, she has been freed from the Immaterium, and as she takes her first steps in a new Equestria, one ruled by the powers of Harmony, only one question remains:

Does Equestria still need the services of a Warmistress?

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.

The portal between Equestria and Sunset Shimmer’s world has closed unexpectedly. Despite Twilight and Sunset’s best efforts, the girls have been unable to come up with a solution. Running low on pages to talk across the dimensional rift, Twilight reads what might be Sunset’s final message to her. However much to Twilight’s surprise, there’s also another message to a different pony.

Inspired by a conversation with Tired Old Man and the story The Last Page, with apologies to Holy.

Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.

Now with an audio reading by Skijarama!

Now with a print version available for order!

A purple Alicorn shows up one night and then vanishes into thin air. Many wouldn't think anything of it besides how strange it was.

Not Rainbow Dash.

Rainbow Dash has met that Alicorn before.

The implication it brings and the guilt that follows leaves Rainbow Dash with questions weighing on her mind.

Luckily, in the crushing pain of reality, she still has friends.
