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.

Prince Flameheart Von Ashen, or simply known as ‘The Flame Prince’ is the Heir to the Royal Throne of The Kingdom Of Fire. Based out of the city of Ashen in the northwestern corner of Equestria. He and his Flame Ponies have lived alone, isolated, and in near poverty for over a millennium after they lost the Great Fire Wars many centuries ago. However they have not remained inactive, and the young Prince will soon find himself the centerpiece of a plot to reclaim their place in the sun.

The year is 1899. The age of the outlaw is coming to the end and the once wild west is being tamed.
But there are still some that stick to the old ways. One of these is the Van Der Linde gang. After a robbery in Blackwater went wrong, the gang left everything they had and went on the run.
But what they don't know yet is that they're about to be thrown into another world.
A world that they don't know. A world that has never seen outlaws of their kind.
A world where the gang can thrive again.

The prologue starts a couple years before the mane 6 is born.

This is a diary of my life as I can remember it, of how I was brought into this world, and my life going on. SO many up and downs, meeting new friends, love, and heartbreak. Also it help that though I was taken from a old life, a new one was born for me, and a mother, who just wants to see her little sun happy!

A creature banished by the Pillars of Old Equestria has come back for revenge. Not for trying to take over Equestria but for banishing him to steal what belongs to him. He returns to Equestria and not even the Magic of Friendship nor Discord Lord of Chaos can stop him. There is one way to stop his actions; just give him what you want!

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 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.

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.
