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

An MLP/Warhammer 40K crossover supplement.

The ponies that have joined the grim and unheroic warriors of the Iron Warriors 38th Company peer into the pasts of their sapien friends. They learn what made them, what drives them, and, just maybe, what may save 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.

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 is the year 3070, and Mankind is once again at war. The battlefields of the future are dominated by fierce, robotic war machines known as BattleMechs, and under their auspice empires have risen and fell. Now with the worlds of the Inner Sphere once again facing the drums of war, two mercenary units have set off on their respective missions, their only tie a common ride upon the back of a JumpShip.

Yet when a cosmic accident causes a misjump, they find themselves thrown into a world that they cannot fathom: a world where magic is a force of nature, where mythical creatures live and thrive, and colorful ponies live protected under the aegis of their monarchs. New choices lie ahead, decisions must be made, and the inner character of Humankind will be put to the test when the question is asked: to conquer, or protect?

--------

It is the year 1023 after the ascension of Celestia and Luna to the dual thrones of Equestria, and Ponykind is at peace. With Luna cleansed and Discord sealed away even more thoroughly than before, all looks bright for the future of the colorful equines. With friendship and optimism, they face each day with hope and vigor.

Yet, when the heavens scream as a foreign object tears its way into their reality, the princesses and their subjects face a new threat that they cannot fathom: creatures and machines from a world of death and darkness, where magic is unheard of and the avarice of powerful men drive the engines of war to crush the innocent under their bootheels. Can they survive the coming of these coarse beings, and can they maintain the magic of friendship in the face of Man's Inhumanity?

A crossover with the Battletech universe, though this is an alternate BT timeline of my own devising. [WARNING: Fandom related material and fanboy rant to follow. Non-Battletech fans won't care, read at your own risk.]

Because **** the Word of Blake and their munch-tastic "armies from thin air" BS. Yes, I know the Clans were almost as bad, but at least they had some sort of justification in-universe. Wobbies? No. Just no. I don't care that it was 15 years, you don't go from "fringe group of mutually-antagonistic and argumentative sub-groups following various degrees of religious mania" to "WE ARE THE SPACE NAZIS ALL WILL BOW BEFORE US" like that.

So for BT fans, this is a 'verse where the Second Star League is still around, the Wobbies still had their temper tantrum though it was smaller and more in line with a bunch of religious fanatics. No stupid "knock everything down for ClickyTech" Wizkids/Fanpro approach, nor any "hey let's shove a bunch of cheesy Level 3 stuff at the players to make the game even more complicated" Catalyst Games stuff. This is just good ol' fashioned 'Mechs wailing on each other, only with ponies. Who will also be wailing on 'Mechs. GLORIOUS.

Set after the Legacy story line. A crew of Mandalorian commandos make a blind jump through hyper space after flying into an ambush and end up crash landing in an uncharted star system. Unfortunately for them and the races that call this star system home, the Deathwatch are close behind and looking to finish the job.

Inspired after playing a lot of Star Wars Sagas and watching way too much Friendship is Magic.

Nines knew he was always fated for something; yet he never knew what it was. Perhaps, after dying at the hands of that traitor and awakening in a new world, he would finally find his true purpose.

Now that we've stopped the world from ending, I hope you're ready to face the consequences of your action! See you in court, the honorable Princess Celestia will be attending this historic event and she'll make sure justice is served!

In a remote corner of the Solana Galaxy lies a backwater planet called Veldin. Nothing important ever happens there. Nothing exciting, either. Ratchet, a Lombax with no idea of his origins, is beginning to grow bored with his life, and dreams of excitement. He wishes on a falling star for some excitement to find its way into his life.

The falling star answers by crashing into his home in the form of a basket carrying a tiny creature with a horn, a pair of wings, and four hooves. The name on the basket reads "Twilight Sparkle".
