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.

It has been two hundred years since Celestia’s funeral, and Equestria has changed. Mighty ships sail between the stars, great cities scrape the skies of half a dozen worlds, and what was once a humble nation has become a vast empire.

And now, Twilight Sparkle writes to her dearest mentor once again.

As of Season 4, LttS is fully re-integrated with canon.

Jacob was a sad 19 year old boy who had a crummy life with his adoptive parents that don't care that much about him, but themselves. At times, he wanted to end his life, but he didn't have the guts to kill himself. One night however, he saw a shooting star and made a wish.

His wish came true... sorta.

He wakes up in the form of a werewolf and ends up saving the life of a pegasus who treats him as if he was a normal person. Could this world be better than the one he lived in when he was human?

Equis has fallen. Long ago, those few gifted with immortality left their dying world, searching for a new home.

That was ages ago. They have been adrift in space for an eternity, and they have found nothing to brighten their spirits. They are starting to lose hope that there is anything for them out here.

However, what they don't realize is that their journey has just barely begun...

-GM, master of Immortals.
