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 Entrenchment

The 38th Company brought many strange and novel things to Equestria.
Technology beyond Canterlot's wildest fantasies. Horrors beyond its bloodiest nightmares.
War, strife, blight, and the dominion of monstrous gods long hidden from the eyes of Equestria's innocent populace.

But the planet known as Centaur III knew the touch of dark magics and evil cults long before the Iron Warriors took their first step upon its soil and constructed their blasphemous idols.
The plot to plunge the world into darkness left many wounds and ancient grudges to fester.
The story of the thestrals, the bat-winged soldiers of the Lunar Guard, is one of misery, bitterness, and betrayal. Their history is little more than desperate quests for power and anticlimactic failures, all mere footnotes now as the survivors quietly return to service under their humbled, purified Princess.

Alas, some scars do not heal.
You reap what you sow.

This story is a sequel to Entrenchment

An Age of Iron story.

At last, Ferrous Dominus is (mostly) secure.
Centaur III has been (largely) pacified.
The enemies of Chaos and Equestria have finally been crushed (probably).

But victory is merely a prelude to the next war. The Imperium of Man and the pitiful, far-flung holdings of the alien await the Iron Warriors and their new allies, ripe for conquest and plunder. With a new home world and a new ally under their thumb, the 38th Company at last turns its attention on a galaxy ablaze with constant war, seeking new victims to fill the bellies of their ships. The gentle but resourceful equines of Equestria travel with them, taking to the field not out of malice or avarice but gratitude in at last fulfilling their grave debt to the Legion.

But in the depths of the void, far beyond the fleet, beyond the veil of the Materium itself, Chaos is not idle. Plots advance, blood spills, and ancient evils seethe.

The light will be extinguished.

This story is a sequel to Entrenchment

Boarding actions are often frantic, desperate assaults. Men are launched directly into the greatest bastions of the enemy while guns that can level city blocks roar around them. Boarding soldiers are swarmed in minutes by all manner of defenses and opponents, trying to wreak what havoc they can within a vessel's belly before they're overwhelmed and extinguished. Incoming fire from their own ships continue to pound away at their target the entire time. Depressurization, incineration, and rad-flensing are all common ends to the life of the boarding trooper, and as often as not their death comes as a result of their own sabotage.

Pity these courageous souls who take their weapons to the hearts of giants.

Being a soldier is something most equate to honor and the highest respecting position in the world. Some soldiers offer the ultimate sacrifice for their country, others come home in one piece. Big Mac isn't in the glory business, he just wants to serve his time and come home. He finds there is no such deal with the army.

Having grown bored of the repetition in her daily life at court Celestia decides to slip out in secret during her lunch breaks to explore her kingdom. What started out as a quest to get sweets quickly turns into a first date with Big Mac.

Captain Flowers thought it would be just another ordinary day. Be there for his men, keep the fighting to a minimum, and make sure nothing bad whatsoever happened to Church. Just like any other day in Bloodgulch.
And then the little pony appeared and refused to let go of his charge. This was going to be interesting...

This story is a sequel to Keeping It Simple

Octavia has fought hard in her life for three things: her art, her career, and her new boyfriend. She never learned to stop fighting.

It's a mistake that might cost her two out of three of the things she's fought tooth and tail for. She's still figuring out which two.

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.
