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 Ponies, Pirates and Peculiar Psychopaths

Chrysalis has been driven out of Canterlot, her invasion defeated. However, an old friend from her time before becoming queen is more than happy to help her succeed with her plans.

Will these two achieve their goals, conquering pony-kind and ruling over them with iron fist and hoof? Or will they be stopped in time, preserving the peace that Equestrian has known for as long as can be remembered? There is more than just dreams of world domination at work, though, this is personal for Chrysalis and her rediscovered assistance.

Hopefully, the line that 'Evil never triumphs' will prove to be correct, or else a drastic change is going to descend upon not just Equestria, but the entire world.

Thanks to Avatar of Madness for the coverart.

This story is a sequel to Aegis of the Hive

Natural selection. It is the byword of every changeling queen who has ever lived. The chief resource that has always curbed the hives' growth used to be love. Now though, with Queen Twilight Sparkle's bloodline capable of producing love on their own, the old guard of changeling morality has seen fit to acquire this ability for the next generation before removing all of their future royal daughters' competitors.

Some queens are far closer to this goal than others.

Editor in Chief: A Bitter Pill, and Boldish42

In the wake of Chrysalis' failed invasion, a different hive breaks tradition and steps into the light to open relations with Equestria. The ever eager scholar, Twilight Sparkle, uses this truce as the perfect opportunity to learn more about this enigmatic race. Unfortunately, or maybe fortunately, she will learn all there is to know about what it means to be a changeling.

But will Twilight lose herself in the hive, or will she regain what she has lost? Only time will tell.

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!!

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.

*HIATUS UPDATE 10/15/2018: There is currently no set schedule for the remake of this story, but I assure you that it still has not been canceled. I get regular comments, favorites, and emails that all point towards this being a beloved story worth finishing, so one day I will do just that. Thank you all for your time and patience!*
Ever since they were little colts, the Flim Flam brothers had a dream; a dream to make a wondrous machine to set their lives on the fast track to success. The machine, known as the Super Speedy Cider Squeezy 6000, was missing just one component to make it all complete. Just one elusive item that no sane pony or pony with values would ever consider using:

Fresh dragon's breath.

Guess what I am.

I was taken from my home, my family, and my wings were slashed. I am no longer a person, I am simply a cog; a cog in the Super Speedy Cider Squeezy 6000.

This is the beginning of my wonderful tale.

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 Nigel M Chalmers, Emperor

(15/10/2015) Turned status back to incomplete pending an Epilouge and Alternate Endings chapter as per comment suggestions.

After being banished by Celestia for his misdeeds, the alien Emperor of the Crystal Empire is back... and out for revenge.

Emperor Chalmers is not a happy space man. After being stabbed in the back by Equestria, he was sent to the depths of the Underworld. Kicked out for causing too much trouble for the wardens, Nigel now has the chance to take back his empire and show Celestia just how disappointed he is with her.

This time things will be different. This time he has friends.

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.
