WARNING: Major spoilers in the comments. Takes place several months after the end of season four. (Not a Da Vinci Code crossover, BTW!)

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.

Curious about Five Score? Come check out the story that inspired dozens of side fics and been enjoyed by bronies for years!

Original Synopsis Even though MLP:FiM ended a few years ago, my friends and I still loved the show. Stories, merch, fan art, I loved it all. Things started to get a weird though when I found myself with a cutie mark appearing on my leg. Humans aren't supposed to get cutie marks, so where the heck did this come from? And what's going on with my hair?

More Detailed Synopsis: Five Score is an action/adventure story of the human-to-pony transformation genre. It’s unique from most transformation stories because the transformation itself is not really the point of the story. It’s the inciting incident that raises countless challenges that must be resolved. They are on earth, as a pony, and need to fix this before things get worse. Think about yourself in their hooves for a moment. How are you supposed to change back or even figure out what caused it in the first place? How are you supposed to get food or do anything on Earth without being spotted by humans? If you are spotted or captured, how would you escape? How does one even open a door with hooves!? Did anyone else on Earth get changed as well? How could you get the word out to the other ponies who are themselves hiding? Is it worth risking travel across the country to reach the others? Which of your friends would you trust to help you deal with this? And why did you turn into this particular pony? Surely it wasn’t random chance, right?

These challenges are the tip of the iceberg in this full length adventure novel There’s a lot of humor, many tense scenes, and hell maybe even a war.

But don’t just take it from me, Look what random people on the internet are saying about Five Score, Divided by Four

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.

I'd heard about the TV show My Little Pony: Friendship is Magic from my college roommate who is way too into the show. Disturbingly so, actually, but good gravy I would never watch the darned thing! What am I, five? I've got better things to do with my time than watch a silly little girl's show. However, that didn't stop... something from transporting me into the world of the show, so here I am... in Equestria... trying to get home. This is gonna be interesting.

Special thanks to GuyFace, Jack Kellar, Storm Shaker, Spiffy McSquee, and Goober Trooper for helping me with this one!

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Mood Wings - Observations on Pegasus Body Language.

When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

Twilight Sparkle is a gifted student and scholar. When she attempts to harness her creative side by writing a science-themed sensual romance novel, however, things rapidly get out of hoof. Can her friends stage an intervention before she humiliates herself (and them) at a prestigious literature recital?

No. No, they cannot.
