It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

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

This story is a sequel to Dash of Humanity

I'm stuck in Equestria, which reminds me of the dark ages. Instead of internet and fast-food, I have Rainbow Dash. She's been asked to help me learn to fit in... I'd like a refund.

I suppose we got off to a good start, aside from being told that after all I'd done I'd never see Earth again. So long as I can look on the bright side of life, and not get arrested for running pranks on everypony with Dash, I might just survive long enough to find my purpose in Equestria. So help me, however, if I get any vegetable related cutie marks I will choke a Princess.

Have you ever woken up as a vegetarian cartoon pony? I have, and she won’t shut up about it. I’m stuck in her body as our minds swap control and our memories blur. I can’t seem to do anything right, and it’s even worse when she’s in charge.

Now, we’re in a back and forth war for control of her body. I just want to eat meat again, and have a little personal space. She’s convinced I’m hitting on her friends and trying to score. I’m not sure I can survive the rest of the day, let alone until we fix this.

She's going to meet her extended family for the first time and wants nothing more than to make a good impression.

After all, it has been over ten years since the portals to the human world were opened, ponies do this all the time now right?

This fic is a series of short, slice of life stories about a pony who loves soft clothing adapting to life in the human world.

I adapted this old fic of mine from it's horribly done greentext version into prose so I can stop being so ashamed of it and finally write some more. Hello PiE threads!

Have you ever had a dream that just seemed so real, that it was impossible to say for certain that it was even a dream at all? A dream that, despite all of its impossibilities, seemed to re-write your entire perception of reality, re-writing your sense of what—and indeed, who—you are? Accepting change is hard enough as it is. But when you're a somebody who wakes up as a somepony, how do you cope with the impact such a drastic change has on your mind and body? With changes like these, it must surely just be a lucid dream—albeit a suspiciously accurate one—just brimming with potential and ripe for exploration. So you might as well suck it up and make the most of these distressingly…unusual circumstances, and seize this psychological adventure before you wake up and the dream ends.
After all, this couldn't possibly be real, so the dream must come to an end eventually…right?

The nation of Equestria has been exploring their little slice of the universe for some time now. From launching probes into deep space, to landing ponies on the moon. Sending things beyond the grasp of their planet has become almost routine. However, with every mission into space, there comes a time when the voyage must end. What happens when Equestria experiences the end of a voyage that they didn't begin?

Touch, Smell, Taste, Hearing, Sight

This is the order the five senses develop in for foals as they rest, cradled in the warm safety of a mother’s womb. But for one, her womb was a thorn bush in the dark of night. For one, the safety and warmth that should have carried her into the world was replaced with pain and cold.

These are Nyx's first hours.
