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!!

Chrysalis sent Twilight deep into the abandoned caves beneath Canterlot to stop her from interfering with her conquest of Equestria, but what if that was not the first time Twilight has been down there. And what if Celestia was not the first individual to take notice of Twilight's potential, nor the most powerful. What happens when the hunger for love clashes with the hunger for knowledge. And which will Twilight choose?

What if Spike had been home when Tirek destroyed the Golden Oaks Library, and had been killed? What would Twilight do? More importantly, who would be able to stand in her way and stop her when she delivers retribution to those who have caused her to lose everything? After she defeats Tirek in combat, she turns her focus on all of Equestria, and those whom she lays blame upon for the death of one she held dear to her.

With the combined powers of all the princesses inside of her, and a deep anger within her soul, can she be stopped, or will all of Equestria answer to her wrath?

Written for the Twirant's Kingdom Competition in the Tyrant Sparkle group.

When Twilight loses control of her magic, she finds herself in the realm of the the eternally damned, Tartarus. In order to survive she is forced to learn and change. However, when Twilight finally escaped from Tartarus, how will Equestria deal with a Twilight who has been forged in hellfire?

Author's Note: I want to point out that the Dark and Gore tags are not all consuming. They are there only by necessity. There are going to be some dark material in here, but nothing grim.

On the same note, Twilight is the only anthro in the story, and there is an in-story reason for it, so don't let that big nasty Anthro tag scare you.

One final thing. It has been some time since I've done any real work on this story. To make clear how long, this portion of the author note was added July 5th, 2019. This story is currently sitting in that little area between "Hiatus" and "Cancelled". Time will tell if I revitalize it.

This story is a sequel to Fallout: Equestria - Fall of a Hero

Saying goes that in the Equestrian Wasteland, no hero lives forever.

History has shown time and time again that even the most promising of uprising heroes may fall to the wasteland. Temptation is lurking left and right, and once one has given in; has embraced the insanity of the Equestrian Wasteland, it's very hard, maybe even impossible, to get back on the path of light.

This is the story of how Equestria's favorite and most well-known heroine fell to the wasteland - and of what happened in the years after.

Sequel/Epilogue to Fall of a Hero.
