Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

Erin has been plagued with strange, often painful dreams her whole life. She has a strict medication regiment she has to ahere to in order to keep her dreams and the strange other personalty she shares her head with at bay. On her twenty fifth birthday however her life takes an even greater turn for the bizarre when she discovers a cutie mark has appeared on her hips. Princess Celestia's cutie mark. Now she's changing into a pony with no clue as to why, and the only help she can turn to may in fact be her greatest hindrance.

Set in the TwistedSpectrum's Five Score, Divided by Four setting. If you haven't read it yet I'd recommend giving it a look. Very interesting concept. Though the whole time I was reading it I kept wondering where the Princesses were. He said he didn't plan on using them so I decided I'd have a go at a side-story in his cool universe. XD

Rachel was just driving home late after a crap day of work when the other car hit her.

When she woke, she was two feet under. When she dug herself out, she was in Applejack's body.

As if that wasn't enough, she's been called to the Big Apple to help the other Elements of Harmony deal with what's been causing people the world over to wake as ponies. So, Rachel's gotta get from Upstate New York to New York City. Not a big deal. Except whoever buried her in that shallow grave off Highway 5 has found out she woke as a pony, and they're looking to put her back in the dirt.

Now, Rachel is running. Running to the city on hoof. Running from her mysterious pursuer. Running for her and Applejack's lives.

Part of the PonyEarthverse group.

When John suddenly finds Luna's cutie mark on the side of both his thighs, a chain of reactions begins that is as far as he knows, irreversible. Are there any other people that are changing? Or is he completely alone in this world?

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.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Hi, my name is Markus.

I thought it was going to be a normal Sunday morning. Boy, was I wrong. Not even out of my bed I discover that I am now Rainbow Dash... and I'm still on Earth. In wake of my sudden change, I try to handle the situation with my knowledge gained from the fandom, my inner brony writer helping me along the way. However, as I soon find out, I'm not the only one with this problem...

Just a self-insert thing I started to get rid of a bout of writer's block. I don't care if it's liked or hated, so enjoy. Please remember, criticism is greatly appreciated, as is praise.

EDIT: For other stories in this universe, PonyEarthverse

This story is a philosophical and comedic telling of my journey, becoming one with Fluttershy, after waking up one morning quite yellow and quite confused.
