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!!

Ponyville has grown boring for Rainbow Dash. Sometimes, an entire week will pass between monster attacks.

What's a mare of action to do when her neighbors are all celebrating apples and hard work? When the weather bureau insists on gentle showers and sunny days, instead of something more exciting?

She has to find adventure, obviously. And when an airship captained by a pegasus pony flies through Ponyville one lazy summer day, dragging a flying iceberg behind it, Rainbow Dash realizes this might be the opportunity she's been waiting for.

But nopony ever said adventuring was easy.

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!!

When a colt named "Bad Dude" storms into Celestia's personal study and declares himself as her latest arch enemy, the Princess can't help but nearly gush from the sight. As perhaps the cutest villain Celestia has ever encountered, she hurriedly calls for Luna to meet him as well.

But is there more to "Bad Dude" than his cute exterior would suggest?

No. No there is not.

Now with a youtube reading! HERE!

Applejack realizes one morning that Rainbow Dash has apparently moved in with her. This discovery surprises Dash more than a little, too, and sets off a chain of events neither could have imagined.

The original minific version of this story came in fifth in the Dec. 2015 Writeoff Association contest, "Things Left Unsaid." And the full, three-chapter-and-an-epilogue version won 3rd place in The Fourth AppleDash Contest: A Little Twist of Lemon using the categories "A Life-Changing Event" and "An Important or Memorable Date."

Friends discuss how bananas can be quite dangerous to the average pony.

Author's note: I enjoy consuming bananas so much. So much that I actually wrote a ponyfiction about them. This is something I wrote in an hour. The only free time I seem to have nowadays.

The world spins, years pass, and everything comes to an end. Except Celestia. She sits on the shore of the last ocean, watching and waiting for her own chance at death. Because everything comes to an end if you wait long enough, and Celestia is patient indeed.

Princess Celestia has been keeping a dark secret from her subjects for a very long time.

It's not an easy truth to tell, but if anyone can accept her after learning it, it will surely be her most faithful student.

All Twilight had to do was finish Starswirl the Bearded's final spell. She didn't have to become undead, seal her soul in the Elements of Harmony, or enlist her friends in an effort to fix everything... but you have to play the hand you're dealt.

Even if it's rotting off.
