This story is a sequel to Iron Hearts: Book 2 - Ferrous Dominus

An MLP/Warhammer 40K crossover, part 3.

The formal negotiations between Equestria and the Iron Warriors have failed. Yet peace and even cooperation between the harmonious ponies and the corrupted militants blooms in the dark corners of Canterlot and the open streets of Ferrous Dominus. The Elements of Harmony are safe, trade flourishes, and cautious meetings grow into lasting friendships as an unsteady calm descends upon both forces.
Even the Tau threat seems to have mysteriously vanished as the Iron Warriors refuse to assault their hideouts and risk springing the traps of the Fire Caste.
But the Tau have not vanished. The Lamman Sept of the Tau Empire, the Fire Caste's hidden dagger, have come to grips with the slumbering giant looming over their doorstep and have moved forward into the final phases of their plan. Fleets ply the void, hunters stalk the orchards, and in the depths of the badlands a strange device is rapidly assembled for purposes unknown.
The Tau alone know that time is running out, and more than just the fate of Centaur III hangs in the balance.

SIGNIFICANT POSSIBILITY OF EXPLOSIONS.

During the first war with Tirek, Princess Celestia sends her sister Princess Luna a very short letter. Although the letter could easily fit onto a single page, Celestia uses two.

Sometimes the medium speaks louder than the message.

Written for The Writeoff Association's "Princess Not Included*" contest.

This story is a sequel to Why No One Messes With Celestia

In the wake of Celestia's return to Equus, the ponies have worked tirelessly to prepare for the arrival of the Ascended. Defenses have been set up, weapons prepared, allies warned, but most important of all in the minds of both Diarchs, a cure for the Indoctrination has been pursued.

The Ascended, or the Reapers as they are known to the rest of the galaxy, are not amused. They attack in force, unwilling to stand by and let this small, barely space-worthy race of unascended quadrupeds neutralize their most effective weapon in their march towards galactic cleansing.

Now they too shall learn to fear the dark, and the Princess who controls it.

Ponies have spread to the stars thanks to advances in technology. In the advanced and luxurious Solar Explorer, Celestia travels to the first extra-solar colony world set up by her little ponies. Unfortunately, events elsewhere in the galaxy, unknown to them, have set in motion a cycle that has been repeated for countless eons… the reaping of sentient races. A Reaper dreadnought confronts the Solar Explorer, intent upon indoctrinating the leadership of the ponies and bringing them to heel.

Said Reaper quickly learns exactly why Celestia has earned the title Unconquered.

A Mass Effect crossover oneshot.

Now with a reading done by Scarlett Blade! Check it out!

The ponies try to make it to Earth to save all humans from themselves. However when they arrive, they're too late. :(

Almost a year after what seemed to be the concluding battle in Celestia's great crusade against necromancers, something Mortem believes to be borderline discrimination, he discovers one of Celestia's armies setting up camp just outside his stronghold.

Not wanting to jump to any conclusions or risk angering the very powerful Princess, he concludes a diplomatic solution would be the best way forward. And so, he writes a letter.

Normally a fic like this one-shot goes the followingway.

Equestria appears on Earth.

Earth get's magic poisoned.

Conflict ensues between pro and anti-conversion forces on both sides.

Then Author tracking occurs depending on how much you like humanity as a whole. Yada yada yada.

This fics merely takes two simple facts about the Bureau genre and changes them: first the idea that Celestia herself is leading, or even aware, of the Bureau.

And second, that the earth attacked is a real life esc earth.

No, the rogue Bureau decided to attack Earths belonging to multiple other shows, books, movies, games, etc....and none of them are all that happy about it.

They also don't really do that well at the conquering part.

Middle-earth. A green land of farmers. Long ago, it was inhabited by great warriors. Now, its violent history has been mostly consigned to history, with only small groups holding to their ancient ways.

Better known as New Zealand.

Mount Ngauruhoe. A towering volcanic peak of black stone. Currently quiet, it may yet erupt again, once more filling the land with smoke and fire.

Better known as Mount Doom.

With the Barrier closing in, a group of devout (and extremely psychotic) Tolkienites has noticed unusual amounts of activity from this famous volcano, and they decide to test a theory. The Barrier may destroy any humans that come in contact with it…

…but what about fallen Maiar?

This is what happens when I write tired and drunk, apparently.

After the heat death of the universe, nothing remains.

Except for Celestia, of course, and her immortal sun.

Rated Teen for profanity, fantasised Celestia/Luna shipping and prejudice against transdimensional immigrants.
