This story is a sequel to Iron Hearts: Book 4 - Emerald Dawn

An MLP/Warhammer 40K crossover, part 5.

With their plan established and put into motion, the 38th Company begins the long and unwieldy task of planetary defense, fueling the arcane energies that may yet unsteady the Empyrean and spare their fleet from an enemy without number or mercy. The inhabitants of Centaur III and even the abandoned aggressors help where they are able, but as their foes grow in number and destruction spreads across the planet, the war for the Centaur system has become a bloody race against time.
All the while, the grim culture of the Chaos marauders continues to mingle with the enlightened benevolence of their equine allies. Tempers fray and allegiances blur. But the die has been cast: Equestria and the Company will survive together, or be snuffed out together.
And even should they succeed, what future awaits these unlikeliest of friends?
For there is no peace among the stars. Only an eternity of carnage and slaughter, and the laughter of thirsting gods.

ALL THE EXPLOSIONS. JUST, ALL OF THEM.

This story is a sequel to Iron Hearts: Book 1 - Planetfall

An MLP/Warhammer 40K Crossover, part 2.

Celestia has handed down her order. The Iron Warriors must be defeated and driven from the planet, lest the corrosive grip of Chaos infect their world. With great reluctance, Twilight and Company depart for the Iron Warriors fortress-factory in order to confront the Chaos Warsmith. However, in this mission it is not the might of the enemy that will be their greatest challenge, but their own burgeoning friendships with the admittedly less-than-saintly members of the 38th Company.
At least until the Iron Warriors actually consider them a threat. Then it's totally their military might that will prove to be their greatest challenge.
All the while, the Tau forces lick their wounds and plot their next move. They are far from defeated, and the Iron Warriors have little inkling as to the aliens' true purpose.

MORE EXPLOSIONS!!

This story is a sequel to Iron Hearts: Book 3 - The Sept Lamman

An MLP/Warhammer 40K crossover, part 4.

The Tau threat has passed. The fleet that once thought to sweep aside the tainted pirates of the 38th Company has fled the system. The Lamman Sept is broken, demoralized, leaderless...
... And victorious.

With Lamman's plan put into motion, an alien horde hurtles through the Warp toward the Centaur system, its soldiers without number and thirsting for violence. Equestria's heroes must find a way to stop them, or the entire planet will be overrun with ease and its inhabitants butchered. While they could afford some pretense of neutrality and disinterest in the fight between the Iron Warriors and the Tau, now it is their world that lay in the crosshairs of the foe. Ponykind will need help to survive, and they look to the forces of Chaos for aid. But is there any hope to be found in the darkness?

EXPLOSIONS ARE IMMINENT.

An MLP/Warhammer 40K Crossover

The Iron Warriors 38th Company has landed in Equestria, entrenching themselves like a barbed hook. They hunt the aliens of the Tau Empire, intent on destruction and pillage.
A small squad is dispatched on a reconnaissance mission, only to find that there is intelligent life on this world besides the feuding space-farers.
Will these improbably adorable and friendly equine aliens turn the damned warriors of Chaos from their blood-soaked path, cleansing them of their dark legacy with the magic of friendship and harmony?

No.
No, that isn't happening.
EXPLOSIONS!!

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.

It was supposed to be a simple task: drop Cerberus off at the Gates of Tartarus, the prison doors for Equestria's greatest and most terrible monsters. Little did Twilight know it was host to an entirely different prison: the SCP Foundation.

Twilight is enthralled with the sheer amount of knowledge and power the Foundation contains. They are likewise willing to bring her on board. After all, who can stop a black ops facility that doesn't officially exist?

Celestia, if she has any say in the matter, and she promised there would be hell to pay if the Foundation harmed her student.

Coming straight out of FTL, Captain Amelia Finegold barely has time to blink as her ship, Cobalt Blue, crashes into an unknown vessel in deep-space. Struggling to get ahold of an unexpected situation, things take a turn for the bizarre when she finds out the other ship isn't driven by humans. Or even occupied by humans at all.

One moment, Twilight is asleep. The next, lights and alarms blare as she comes to grips with an unexpected emergency. Problems crop up one after the other. Irreparable damage, wounded ponies, and a new alien species?!

Set in an alternate universe where Equestria became a space-faring empire.

Small note: Some revisions have been made, thanks all!

As a former high ranking Forerunner Warrior Servant whose career spanned thousands of years, the Ur-Didact has seen many oddities, horrors, anomalies, and other things that defy the imagination of younger beings. However, an unintended passage through a slipspace portal during the attack on New Phoenix and into unknown alien territory may produce sights that even the Didact would find outlandish. Injured and far from familiar surroundings, the Forerunner is in a bad way. To make matters worse, a great evil is rising in this alien world and Didact is about to find himself right in its path.

This story takes place after My Little Pony: Friendship is Magic season 4 and takes place immediately right after Halo 4 ending.

Very special thanks to Word Worthy for being the editor of this story.

Until yesterday, my life was no different than anybody's. Go to work, pay the bills, sleep. Today, I woke up to a world without humans. The streets are empty, the power grid is running down, and not another soul is in sight. That might not be the worst thing, if I wasn't also a pony.

Where is everyone? Why is this happening to me?

Will l stay sane long enough to starve?
