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.

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.

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!!

The home world of the Transformers - Cybertron - is dying. Energon, the lifeblood of the Transformers, is in scarce supply, sparking the one decision Optimus Prime has to make so that his race will survive. Optimus leads the Autobots in an attempt to man the last transport off his dying home, a ship known as The Ark.

Meanwhile, Megatron and his Decepticons have found a new world rich with energy and plan to suck it dry in a ship called The Nemesis. As both Autobots and Decepticons race towards the space portal to the new world, they must fight for their lives when the true end of the Cybertronians is near.

The once Golden Age of Cybertron is over... These are the end of days.

Or so it seemed....

When a Space Bridge accident sends Grimlock to Equestria, he must locate the other Dinobots or become enemies to the strange inhabitants that rule this new world.

But what happens.......when more than just Dinobots are sent to Equestria......

With Fall of Cybertron now released, this is the continued story of that horrid war, battles will be fought, heroes will fall, and the Autobots will never sacrifice freedom.....no matter what species they are fighting for.

Sequel to The Transformers My Little Pony Crossover. After the rebirth of Cybertron, the Decepticons return to Equestria in full force to invade it! As the Autobots try to liberate the ponies, they will gain help from unexpected allies...

Twilight Sparkle finds an ancient star chart which shows the location of another world, Earth, as well as a powerful teleportation spell capable of interstellar travel. Princess Celestia allows Twilight to go to the other world for exploration. However, due to the Changeling invasion during the royal wedding, the negative energies it produced also frees Discord from his stone prison, who also decides that Earth should be his new playground. Meanwhile the Autobots continue to defend Earth from Megatron, and his Decepticons; ignorant that a new player is about to release chaos upon the world. And Megatron is not about to let another would-be conqueror steal his prize. Equestria also has it's problems when Queen Chrysalis returns to Canterlot, bent on usurping Celestia and Luna.
Twilight Sparkle, and Optimus Prime must save two worlds from three powerful villains.

(This takes place at some point during the 20 year time frame between The Transformers G1 series Season 2 and Transformers: The Movie; and 1 week after the Royal Wedding in Canterlot.)

The war between the Autobots and Decepticons ravaged their home world of Cybertron, four million years ago in a battle that lead to the loss of many lives the two factions landed on earth through a space bridge, now only recently reactivated their war has been reignited on our world. Several years into the conflict Decepticons have began to attack human resources at an alarming rate, prompting Optimus Prime to believe that they are building another space bridge. With Autobots and resources at an all-time low he reluctantly calls upon the aid of the Dinobots. In the cold land of Greenland Grimlock notices the monster that made him, the mad scientist Shockwave, losing all control he attacks him head on, sending Shockwave, himself and several other Decepticons through the portal. Now Grimlock is in a world full of colorful, magical ponies... THIS should be interesting...

Rated Teen: For sequences of violent robot fighting action and some possible adult humor further on, not sure if I should add dark tag, maybe if someone says I need it I'll put it up.

P.S. if you give it a thumbs down please tell me why you didn't like it, that would be appreciated.

My name is Frosty Winds. I was just your typical, rank-and-file Enclave scout. I had an ordinary life, living in contentment among my loving family and good friends. Things were good.

At least, I'm pretty sure that was the case; I honestly can't say for certain anymore. One moment, I was being recruited to take part in a routine Wasteland scouting mission, and the next moment I wake up as a prisoner of the Steel Rangers.

On the bright side, I’m not missing much. Just all of my memories. And my left foreleg. Nothing important, really. Pile on a disease I’m not vaccinated against and being a few clouds short of a weather system probably doesn’t make any of this much better.

As if that wasn't enough, apparently I made a deal before I lost my memories. If I don't complete my task I agreed to within a month, I'll die. Of course, it would be helpful if I could remember what the agreement was.

So here I am, floundering aimlessly about the Equestrian Wasteland. I have absolutely no idea what happened, what I should do, or how to uncover the secrets that lie within my stolen memories.

Help. I need an adult.
