Nighttide Star, born under the moon of a foreign land, is adopted by the Daedalus Institute of Research and Exploration when her parents are killed in an earthquake. Raised under the company's Labyrinth project, she is hoof-picked for a leading – and as of yet untitled – role for the government. Branded with the serial number LAB-1032, she is all but pure machinery by the age of eighteen.

While running an experiment on a prototype warp drive, Nighttide is lost to the ether and wakes to find herself in Equestria. Lost and injured, she is discovered by a timid mare with wings, and soon embarks on an unexpected journey.

Once there was a monster, whose flesh was made of steel,
A pony’s magic bound her, and she was made to kneel,
She was the pony’s servant, saw her sheltered, safe, and fed,
But when the monster left, it was the pony’s heart that bled.

Takes place seven years before the events of Familiar.

This story is a sequel to What I've Become

It is highly recommended that you read What I've Become before you read this story, since this is the second story in The Humanity Within Trilogy, and you will be lost if you just plunge into this without any preparation.

Also, this story already has a sequel: What I Am!

Things have been turning up roses for me lately. I'm no longer fighting to survive, I have people that I can turn to, and I have my face back, all because of the kindness shown to me by strangers.
But will they continue to help me once they find out what dark secrets haunt my past? Will they shun me for the evil deeds that my abductors forced me to do while I was in their service? Will they continue to protect me from the monsters that destroyed my life, once they realize what kind of monster I really am?
How does one forgive a murderer?

This is the first book of The Humanity Within Trilogy. Its sequel is What I've Done.

I wasn't always like this, a monster, running through the woods on an alien planet. I was once a man. I had dreams, a girlfriend, and a great job.
Then They came. In the middle of the night, They scooped me from my home, and... changed me.

Now I'm a beast, a demon the like of which the world I've become stranded on has never seen before, scraping by on the fringes of society, hiding from the natives, and doing my best to avoid notice.

After all, who could ever be friends with a monster?

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...

(Warning: experimental writing techniques, perspective shifts, classical grimdark, and much less pony than usual)

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

An MLP/Warhammer 40K crossover, part 5.

With their plan established and put into motion, the 38th Company begins the long and unwieldy task of planetary defense, fueling the arcane energies that may yet unsteady the Empyrean and spare their fleet from an enemy without number or mercy. The inhabitants of Centaur III and even the abandoned aggressors help where they are able, but as their foes grow in number and destruction spreads across the planet, the war for the Centaur system has become a bloody race against time.
All the while, the grim culture of the Chaos marauders continues to mingle with the enlightened benevolence of their equine allies. Tempers fray and allegiances blur. But the die has been cast: Equestria and the Company will survive together, or be snuffed out together.
And even should they succeed, what future awaits these unlikeliest of friends?
For there is no peace among the stars. Only an eternity of carnage and slaughter, and the laughter of thirsting gods.

ALL THE EXPLOSIONS. JUST, ALL OF 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.

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!!
