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 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.

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!!

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!!

when evil rules and goodness fails theirs only one hero who can answer the call, and he answers with.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHH!!!!!!!!!!!!!!!

It has been two years since the human TD ascended to become Princess Antares, and he is settling into his role as one of the rulers of Equestria quite nicely. His loyal guard is strong, his palace is awe-inspiring, and he is beloved and worshiped by ponies everywhere. However, when the Element of Magic is stolen by an old student of Celestia's and taken through a magic mirror while he is visiting the Crystal Empire with the Mane Six, he discovers that another world has been very close by during his whole reign. A rather familiar world at that. Deciding that he is the best pony for the job, he takes his two best soldiers through the portal with him to get the Element back. So, pretending to be a foreign exchange student from Canada, he infiltrates of all things... a high school.

He is less than pleased.

On a cold winter evening, I met her, her cheeks chapped from tears frozen from the cold.

We took up talking for a while, and as I listened, I could tell she was out of aces, bound for nowhere.

She had the look of someone running away, with nowhere to go. Fleeing, not advancing.

I had a bit of advice. I've got no clue whether she took it.

I just hope she remembers the gambler whenever she gets to a place she could call home.

This story is a sequel to NOW YOU BUCKED UP.

When a new, strange kingdom of magic is discovered to the far west of Equestria, the Royal Sisters take an entourage and investigate. Which nearly sparks ANOTHER international incident.

Once again, they don't bring Twilight. And ONCE AGAIN, she's left to clean up the mess. Which involves yet another very long letter.
