This story is a sequel to The Princess and I

Ever since the day I decided to give up my old life for a new one I could say that everything's going good. I mean I've got a great girlfriend, an awesome new house and pretty much everything else a guy could ask for. However I'm sure that a lot of guys you look at me funny if I said my girlfriend was a princess and I live in a castle and I'm sure they'd say horrible things about me if they found out that princess was actually a pony who can control the moon.
My name is Aedan Ryan, six months ago I came to Equestria because I fell in love with a pony named Princess Luna. (Crazy right?) Now after having dealt with having to take care of her, a whole new challenge awaits me... one that I and every other man in the universe could never really be ready for...

My name is Aedan and I'm your average run-of-the-mill guy from Missouri. I served in the Marine Corps for about four years, now I've been out for a year and I'm making a living on the edge of St. Louis. It's not the best of conditions for a guy like me to have to deal with, but I adapt and overcome. Then one Saturday morning on my daily jog I ran into something (well in truth she ran into me) I'd never thought possible. She calls herself 'Princess Luna'. She's alone and confused, but most of all, she wants to go home. And guess who the poor guy is that decided to help her.

rated Teen for talking like a Marine and some... 'Adult' situations...

Ninth Captain Fubar Jac'ass is a very good Angry Marine, he shouts his profanities, he kills the enemies of his Emprah real good, and he don't take no shit from no thrice damned Ultrasmurf. So why in the name of Terra has he been assigned to aid a little purple xeno Inquisitor that keeps having him do the most mundane things? And why does he keep going along with them, something here isn't right. And it's making him extremely angry.

I don't own the title art, Warhammer 40k, or My Little Pony Frindship is Magic. Rated teen for lots of angry profanity and potential for bloody happenings.

This story is a sequel to The Lunar Apprentice

Celestia won. Her Royal Guards defeated Nightmare Moon and her army of rogue Lunar Guards. The Shadowbolts were driven underground, and the Lunar Apprentice is dead. And what has victory brought?

Hell.

The Elements of Harmony are separated and useless. The renegade forces of the New Lunar Republic are hidden in the shadows, free to move and strike at will. Confidence in Celestia's rule has been shaken throughout Equestria. Half the Royal Guard is out of commission, and the changeling army is on its way.

Every loose thread is being pulled on; it's only so long before the tapestry unravels.

Celestia may have won the battle, but she also unleashed the Night Terrors. And Equestria may not survive them.

Update 10/14/2015: Featured! Glad Night Terrors is proving to be as strong as its predecessor. A major thank you to all fans and followers!

Discord, for a master of chaos, was actually a very good planner. Despite the confidence that he would bring Equestria to its knees in mayhem, several millennia of experience had taught him to have a back-up, no matter what. And after watching from the sidelines as Princess Luna became Nightmare Moon, he knew he had found an ace in the hole. Despite his defeat, Discord's greatest trick was still to come.

You know what this means: Equestria's greatest Nightmare is back. And this time, she's not alone.

Edit: Featured 9-27-2013, first time I've had a featured story. Thanks to everyone who's stuck by this story in spite of admittedly slow updates!

Rick, finding himself in Equestria, isn't all that happy. For the weeks since he's been there, he hasn't smiled or laughed. When Celestia and the Main 6 take him to karaoke night at a restaurant, they think that this might be what gets him out of his shell.

Rainbow Dash is gone.
Two Years ago she performed a trick to eclipse all others, and vanished without a trace. Everypony has started to get over it, although for five ponies the loss is to great even now. In respect the Wonderbolts do a performance for her at the site of her death. However, a certain Cyan mare is hard to kill, and is loyal to the ends of the universe, she can say that with certainty now, she’s been, and now she’s back. But what is she wearing, and where did she go for two years? Buckle up, for in Equestria there may be peace, but in the 41st Millennium, there is only war.

Now with a sequel: The Descent into Madness

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 )

Princess Celestia and Princess Luna are leading together a combined Army of several different equestrian Races against an supposedly terrifying and unfeeling Enemy.

What kind of Threat are our beloved Princesses are really going to face?

A Warhammer 40K/MLP:FIM Crossover.

Special Thanks goes to ARchy4288, Tyrannosaurus_Tux and AlicornPriest for Editing, Proofreading and otherwise helping.
I can only recommend those guys.

Warning: Silliness inbound.

By order of the high lords of Terra themselves, a lone soldier from the Death Korps of Krieg has been sent to the planet Epona to wipe out its Xeno population. Starting with Equestria, the Korpsman has sworn not to leave the planet until he falls or completes his mission.

However, no Korpsman should fight without setting up a proper trench first, and so the Korpsman must dig...and dig...and dig.

Destroying Equestria is going to take a while.
