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.

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

Sunset's friends ask her for help with a lot of things. Pretending to be Rarity's boyfriend at her cousin's wedding is a new one. It can't be that hard, right? A sharp suit, some expertly applied makeup, and a good backstory and she'll be charming the pants off of the bridesmaids in no time.

But just what is Rarity hoping to get out of this subterfuge in the first place?

Russian translation

After bumping into a rude pony from flight school, Rainbow tells a rather large lie to save face.

Shouldn't have did that, Dashie.

A two part story.

The Festival of Friendship is in full swing, and Tempest Shadow should be languishing in a prison cell, waiting for her punishment. Instead Twilight asks if she’d like to stay with her for the night.
This whole friendship thing might be more confusing than she thought.

(Now with bonus chapter)

While relaxing after a performance, the Rainbooms discover Sunset has scars that she definitely didn't have before the Fall Formal.

One of the positive things about being enlisted in the Solar Guard is all the mares Rainbow Dash could possibly chase after.

A negative? The one she's really after is in the Lunar Guard, and she's pretty… batty.

Dear Celestia,

If you're reading this it means my infiltrators are better than your guards. Boom! Point to Chrysalis. But seriously, don't take it too hard. Changelings are just naturally better than ponies at so many things. That being true, wouldn't it be a lot easier to work with us instead of against us? Don't worry, I'm not talking about another coup. I'm talking about a real partnership, an opportunity that you just can't afford to pass up.

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

Upon gaining access to the multiverse, some people go on fantastic adventures: rewriting history or exploring the vast unknowns of time and space.

Twilight Sparkle had another idea.

Rainbow Dash has rather a poor reputation when it comes to her workload. Everypony always thinks of her as the pony who takes three naps during daylight hours, and four on weekends, and always seems to be looking for something to do to pass the time. All of this is true, of course. But ponies seem to think this means that she must not ever get very much work done.

Can the weather captain for all of Ponyville really be as lazy as she seems? Is that the only explanation for Rainbow Dash's free time and constant napping?

The weather is a full-time job. Twenty-four hours a day, seven days a week. And the worst weather happens at night.

So weather ponies have strange sleeping habits.

Set before the events of the show.
