Twilight Sparkle learns that the trust and goodwill of the Princess isn't always a good thing as she's given the trust of an important assignment. When that assignment turns out to be long-term, how will she handle taking care of a filly of her own? How will she handle this strange new filly, who proves to be much more than she appears. As a matter of fact, she seems to be from an entirely separate universe.

Meanwhile, Second Chance has kept only enough of her memories to know that she isn't what she should be. The wonderful world of Equestria has its own dangers, and she seems to have a knack for attracting trouble. The more of her memories return, the more she wishes she could just forget. But you can't forget when all of Equestria depends on you remembering.

Only one thing's for sure: The longer Twilight keeps this strange filly in her care, the stranger her own life will become, and things she thought she knew about Equestria will unravel before her eyes. Strange ancient devices, an eccentric mint unicorn and her so-called "Equestrian Precursor Society" are only the beginning for Twilight Sparkle as she begins a journey of her own. She too may wish she could simply forget. Unfortunately, it's too late for either of them.

This story is a sequel to Project: Sunflower

After the events of Project: Sunflower, Erin Olsen has returned to Ponyville, happy to pursue her studies in magic. After everything that happened the year before, she's looking forward to spending her days studying and having fun with her friends.

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

Erin will need all of her courage, all of her cleverness and, of course, all of her friends to see herself through what happens next.

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.

Now with its own TV Tropes page

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

I wanted to just enjoy going to Supanova with some friends. As embrassing as losing a bet, my punishment being going dressed as Raven from Teen Titans is, I'm not going to let it spoil my fun.

However, waking up in the world of My Little Pony as Raven herself might spoil that fun. I mean, being an empath in MLP... after the Changeling Invasion at the wedding?

Yeah. I don't see any problems for me from that. Not to mention keeping my new powers under control when they're tied to my emotions and I haven't had all the years of training Raven did.

And let's not forget that my new powers are shadow magic, so basically Dark Magic. I don't see that causing me any problems socially, either. Nope. None at all.

T due to Scenes of Violence, Blood, (hence the Gore tag) sometimes and nudity of a young girl and other things.

Adventure and Slice of Life tags would be here if they didn't go against each other, plus there was no room. Sex tag mostly for when Raven is nude and how she talks about sex and similar things with the ponies at times.

Featured 23/3/2017. Um... okay.

My name is Rachel. Or at least it was. A bad decision brought me to the brink of death. I was "rescued" from that fate by some self-appointed "Spirit of Chaos." Or maybe he really was the devil, I don't know. He promised me a second chance but didn't tell me it would be in the body of a cutesy pony in a world which makes no sense. Worse, I think I've been set up, and something bigger is going on ...

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 The Eternal Lonely Day

On May 23, 2015, the world ended. It wasn't violent, it wasn't bloody, and it wasn't even very dramatic. The entire population of the planet vanished. But they didn't stay gone; almost at once refugees started trickling back. Unfortunately for them, they didn't come back with their humanity intact.

Instead of a single species, the earth is now populated with Ponies, griffons, dragons, minotaurs, and even stranger creatures. What will the remnants of humanity make with their world? Will they remember human achievements, or slip back into primitive ignorance? Learn from our mistakes, or repeat them over and over?

People haven't really changed, only their bodies have. The world now comes with new threats, supernatural as well as mundane. Demons lurk beneath the sea, while strange spirits whisper promises in dreams. Empires rise, dictators control, and ponies have nowhere to turn for help. Nowhere except themselves, and old-fashioned hard work.

This story is effectively an anthology of episodes, each of which will focus on a different time period and different perspective characters.

Latest in the Last Pony on Earth series. If you haven't read that story, start there. This one won't really make much sense otherwise.
