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.

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!!

(Featured on Equestria Daily 8/20/15 )

Equestria has seen their fair share of dangers and threats made to their land by gigantic monsters and power-crazy lunatics. From all of these threats, the Elements of Harmony have been at the ready to combat them through the unbreakable bonds of the magic of friendship.

However, a new enemy bearing incredibly lethal weapons threatens to leave the Elements helpless against unprecedented violence. When one Element and two others are taken hostage, a group of elite soldiers contact Princess Celestia to offer assistance. They're professional and more than capable, but Celestia fears they may have ulterior motives. Not to mention, there's the fact that they come from another world.

Rainbow Six belongs to Tom Clancy, Rainbow Six: Siege belongs to Ubisoft/Tom Clancy, My Little Pony: Friendship is Magic belongs to Hasbro.

Rainbow Dash discovers that she has suddenly acquired a mysterious and ancient power known as a Stand. Soon after, she learns of a cult of evil Stand Users who are threatening to unearth a long slumbering power that could threaten to destroy Equestria as she knows it. Now it is up to Rainbow Dash, her friends, and her Stand, 「2 Minutes to Midnight」, to defeat these Evil Stand Users. Surely a Bizarre Adventure awaits.

This story is a crossover/fusion of MLP and Jojo's Bizarre Adventure. No Jojo characters will appear in it, only themes and concepts from the show/manga. The story will feature at least 24 unique Stands created by me and/or my friend/coauthor. I plan on updating this every Friday. So stay tuned! Comments are both wanted and appreciated.

The scope of the multiverse is so tremendously beyond the comprehension of most beings that, if they were to truly know what it meant, they would break down and be unable to live their lives the way they wished. Most worlds are lucky to be blissfully unaware of the true picture of reality, never to encounter the higher forces and civilizations.

However, when one of those higher forces make contact with one of those unaware worlds - intentionally or not, peacefully or not - everything will change drastically. Sometimes the change is slow, sometimes rapid. Regardless of the pacing, like all change, it is both good and bad. Civilizations have risen from simple worlds overnight and have crumbled just as quickly. Many can't handle the revelation, and those that can are not always the best examples of honor and dignity.

It is often said that each world - each universe - has a Song, and that all these Songs are related, intertwining together in a mesh of powerful destiny among the Spheres of the multiverse.

This is the story of how a certain world inhabited by Technicolor ponies found their Song and how it interwove itself in the Songs of so many others.

This is a story of finding meaning in infinite possibility.

This is a mega-crossover project of immense proportions covering dozens of fandoms. However, it is written in such a way that no previous knowledge of any of them - not even the ponies - will be required. The only warning is that there will be spoilers for any franchise you haven't seen.

There are several side-stories being written for Songs of the Spheres by several authors, and links to them can be found in our Fimfiction group, including links to non-pony related stories. There's also a Discord chat. Lastly, we have a Spacebattles forum. Discussion about the multiverse, setting, and future events can also be found there if you don't mind spoilers.

Has a TV Tropes page now. Needs love.

-GM, master of the Dark Tower

On July 17th, 2023, satellites around the world began to pick up a strange radiation source coming from the North Pacific, just above Hawaii. Just as the US, Japan, Australia and other such nations along the Pacific begin to investigate, something covers the entire North Pacific in blinding light, a loud crack rippling through the air. When the light finally died down and humanity rubbed it's eyes in shock, they saw none other than Equestria.

The first contact had gone well enough, with pony and human delegations meeting in New York, Celestia herself showing up for a moment. They claimed that the appearance of Equestria was purely accidental, a 'magical mishap' as they put it. They established 'Conversion Bureaus' around the globe, establishments for the sole purpose of permanently changing a human into a pony.

As it turned out, this was all a ruse. Shortly after the final conversion bureau was built, Celestia herself declared humanity to be a 'vile' and 'unfit' species, citing examples such as their wars, their pollution, and so on. All at once, the Conversion Centers released hordes of Pegasi and Unicorns, bent on forcibly turning all of humanity into 'peace-loving' ponies.

All at once, millions of humans were transformed. Military bases sabotaged. The world couldn't even get a missile out of the ground in time, much less perform a coordinated counter-assault. Humanity simply wasn't prepared for this.

But as it turned out, there were other players in the game. Humanity had gotten out of fixes much worse than this before, and they didn't even realize it. Organizations, unknown to even the world elite, sat beneath the surface of the Earth or disguised as ordinary facilities, prepared to do everything in their power to prevent the extinction of humanity.

As humanity panics, the SCP Foundation takes action.

This story is a sequel to My Little Planeswalker: Shattered Sunset

Upon returning to the human world, Sunset Shimmer finds Canterlot City twisted into a biomechanical hellscape, with all living things transformed into grotesque mockeries of their former selves. Led by the human Starlight Glimmer, the forces of Phyrexia loom omnipresent over all aspects of life.

Joining her six closest friends, Sunset is now faced with a seemingly impossible task. Can the magic of friendship find a cure for phyresis, or will the world be forever doomed to compleation?

In a boundless multiverse there are equally many stories to tell. While planeswalkers across time and space compete in epic struggles for their own ideals, the ponies of Equestria have many tales of their own to share.

A series of short stories in the My Little Planeswalker multiverse, set between the events of Twilight’s Spark and Shattered Sunset.

After Starlight Glimmer's misadventure beyond the Magic Mirror, Twilight Sparkle creates an artifact that will allow its wearer to travel between planes of existence without allowing excess magic to leak from one world to another and upsetting the delicate balance of worlds.

In doing so, however, she soon discovers more about herself and the spark that awakened the Element of Magic than she could have ever anticipated, and learns of a secret that Celestia had been keeping from her all her life.

Stranded in the world-spanning city of Ravnica, Twilight Sparkle must now seek to understand herself and the strange new plane of existence she's found herself in, and come to terms with her own role in Equestria and the Multiverse.
