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!!

Crossover with the Dresden Files. Sequel to Forever!

For his first task as the new Winter Knight, Harry must travel to the land of cute little cartoon ponies to stop a plot by the Order of Blackened Denarius that threatens both Earth and Equestria.

Warning: Includes massive spoilers for the Dresden Files series up through Ghost Story.

The vampires of the Red Court are vile and cunning creatures, they attempt to conquer or destroy everything around them. Now a small group of the vampires have stumbled across a new world to take for their own, but they did not come alone. Wizard Harry Dresden and Knight of the Cross Michael Carpenter chased after the creatures and now find themselves trapped in the same world the vampires are slowly taking. They must lend their experience to the local inhabitants if they are to fight off the growing horde, and the new Red King.

I will explain the Dresden history as it becomes relevant to the story. So it is not necessary to have read the Dresden books to understand what's going on.

Edited by: NaughtSought

Takes place before the season three finale of MLP, and sometime after the events of the White Night novel. So no Princess Twilight or Winter Knight Harry, sorry. At the time of writing, I haven't read Cold Days or any novel onward, so please no spoilers in the comments.

I do not own any of the Dresden/MLP characters.

Crossover with The Dresden Files.

Pinkie Pie randomly shows up at the apartment of one Harry Dresden, Wizard-for-hire. And then she does ... whatever it is that Pinkie Pie always does. Madness ensues as Equestria's craziest Party Pony inflicts herself on everyone's favorite cynical smartass of a wizard.

My Little Denarians is the sequel to this story.

This fic now has a dramatic reading courtesy of Comma Kazie and Lisa M.
