This story is a sequel to Entrenchment

An Age of Iron story.

At last, Ferrous Dominus is (mostly) secure.
Centaur III has been (largely) pacified.
The enemies of Chaos and Equestria have finally been crushed (probably).

But victory is merely a prelude to the next war. The Imperium of Man and the pitiful, far-flung holdings of the alien await the Iron Warriors and their new allies, ripe for conquest and plunder. With a new home world and a new ally under their thumb, the 38th Company at last turns its attention on a galaxy ablaze with constant war, seeking new victims to fill the bellies of their ships. The gentle but resourceful equines of Equestria travel with them, taking to the field not out of malice or avarice but gratitude in at last fulfilling their grave debt to the Legion.

But in the depths of the void, far beyond the fleet, beyond the veil of the Materium itself, Chaos is not idle. Plots advance, blood spills, and ancient evils seethe.

The light will be extinguished.

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!!

Everyone wears a mask. For the rulers of Equestria, that mask must be impeccable for their subjects. Only around their guards can the two Princesses relax ever so slightly, occasionally showing that they are just as fallible as any other creature. For one Princess, the burdens of her own mind begin to make the mask crack. However, when Private Steel Heart notices that it is, in fact, the pony underneath the mask that is beginning to splinter, he offers to help.

He had no idea such help would first involve getting attacked with a large brush.

Warning: Involves slow-burn romances, lots of feelings, comforting moments, adorable affectionate gestures, lethal amounts of fluff, feel-good auras, and a deadly combing implement.
Takes place around Season 8-9 (ish)

Once upon a time, there were two friends who ran a farrier shop in Canterlot. The oldest fed the forge and used his earth pony magic to produce strong steel shoes, which the younger enchanted with his powerful unicorn magic. They worked together in harmony, creating beautiful shoes for all who visited until one day they met a young mare in their local bar. She was a mysterious creature, overstressed by her job in the palace and needing the company of two friends far more than she realized.

Until one night, when her sister returned during the Summer Sun Festival…

Rarity and Twilight are dating. Rainbow Dash just asked them both out as a joke.

She didn't expect them both to say yes.

Clover the Clever never asked for his life to get so complicated.  It was bad enough tricking a drunk Imperatrix Celestia, war goddess of the Three Tribes, out of her accidental coup against Queen Platinum.  But now the most dangerous pony in Equestria has returned to trade her claim on the sun for a chance to woo him.

On top of that, his erstwhile mentor Star Swirl the Bearded has saddled him with a mysterious magical necklace and a uniquely bleak and pointless prophecy: If he's brave enough, and if he's clever enough, he just might survive Celestia for long enough to break her heart.

Now with an audio reading by ScarlettBlade!

Recommended by PresentPerfect! "horizon gave me the story I needed rather than the one I wanted ... along the way we get some very strong lessons about love, and meditations on the value of a lifetime and what one pony can achieve on their own."

Harry Potter was no stranger to problems, although his always seemed to be far larger than other young wizards his age. After all, Voldemort had tried to kill him as a baby, and twice during his first two years at Hogwarts. Hopefully, his third year in school would be easier, although he first needed to survive his summer with his aunt and uncle.

Between a hectic schedule of daytime chores and nights spent trying frantically to keep up on an ever-increasing pile of holiday work, he was working himself into a frazzle, and that was before finding out that his Aunt Marge was coming to visit. To top it off, an accident has just left him with a tiny purple problem he had never expected: a toy-sized unicorn named Twilight Sparkle.

His problems have just begun. And they will continue to multiply.

During an attack on Ponyville in the middle of the Summer Sun Festival, Princess Twilight Sparkle evacuates the town by teleporting the entire population to safety in Manehattan. It turns out that her idea of safety needs some work. As well as her aim. And spelling.

Meanwhile, on a hot summer day outside of Manhattan, Kansas, Jonagold Bruener had a fairly successful life with few complications. Until while out mowing hay, he had a very strange visitor fall from the sky. And then another. And another. And another....

It was supposed to be simple. Coco would head to the Crystal Empire, design some new uniforms, collect a paycheck and head back home. But a few wrong turns in a confusing castle led her to a place she’d never even imagined. And after a few chance encounters with some very attractive mares, she’s not so sure she wants to leave.
