While out on a cutie mark crusade, the Crusaders happen upon a lone changeling on the edges of the Everfree Forest. After a scuffle the changeling finds itself injured and trapped in Ponyville. Seeing an opportunity to earn their cutie marks the girls take the changeling in, planning to teach it about Equestria.

However what they don't know is the changeling is actually the Commander to the Changeling Empire, and he has his own plans in mind.

But soon events play out for the four as they endure the aftermath of the Canterlot Invasion, and perhaps toughest of all: Each other. Lessons are learned and stories are shared between one another, leading the changeling to question its motives, and itself. Leading it to ask the biggest question of all:

"Can creatures that's special talent is to change its appearance, change in other ways...?"

Life can be a rough gig, and life in Ponyville is no exception. Between pestering Parasprite plagues, dreadful Diamond Dog droves, and colorful Crusader craziness, Twilight Sparkle could tell you that moving to a new town can be quite a hassle. This… is not her story.

Instead, meet Reason. He is not a bearer of one of the Elements of Harmony. He is not a cadet-warrior-pegasus-in-training. He is not a wandering unicorn vagabond living in a dangerous, post-apocalyptic Equestria (that would be silly). No, Reason is a regular earth pony with regular earth pony problems trying to carve out a life for himself and his sister in the not-so-regular town of Ponyville.

Set during the events of Season One, Reason must navigate the perils of a normal pony’s life in a town that is less than normal, juggling romance and duty, and ultimately discovering for himself whether friendship truly is magic... Or, you know, not.

After all, in a place like Ponyville, anything is possible.

Sweetie Belle is compelled to learn magic after Rarity promises to teach her the finer art of dressmaking, but only once the young filly has learned the basics of magic. However, learning magic comes with its own set of complications and bears an unforeseen gift that will change Sweetie Belle's life forever.

Here's a one-shot sequel that takes place four days after Scion of Chaos: An Emerald Treasure

And this is a Multi-chapter sequel that takes place 5 years after the events of SoC and AET: A Heart of Change

Here's a poem that's based around the character Red Timber. (Not necessary to read for the comprehension of the storyline): Red Timber

Following the assassination of Princess Celestia, the Long Night withered the once bountiful Apple Harvests of the Apple family. In the years since, they have been reduced to dumpster diving and street life. Applebloom, unwilling to continue in such a state, violates her elder sister's wishes in order to find help from Applejack's friends, who surely must be better off.

Unfortunately, Applebloom's journey to Canterlot shows her the true fates of the bearers of the Elements of Harmony, who are as unable to help Applebloom as they are to help themselves. Applebloom's desperation grows with each reunion. In the end, she must turn to powers greater than begging to save her own future and those of many others.

After her defeat in Canterlot, Chrysalis awakens deep in the Everfree Forest. Determined to get revenge, she heads North to the unsuspecting Ponyville with plans of impersonating Twilight Sparkle. But will the transformation change more than just her looks? Learn more about the dark Queen, the seeds of corruption, and the power of love as Chrysalis is forced to see the world through an entirely new perspective in "Metamorphosis."

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

Bon Bon's voice is funny, and that's about all that anypony who meets her notices, as her marefriend Lyra soon steals the spotlight with her explosive personality, strange obsessions, and curious beliefs. And why not? Bon Bon is, after all, a perfectly ordinary, boring pony in every way but two: her voice, and the carefully kept secret that she isn't really a pony.

It's been a thousand years. Princess Luna is returned, and the castle staff must scramble to see that she has servants to attend to her needs, and just as importantly, that they look the part. Of course, it turns out that it's rather difficult to find competent servants on such short notice. A hooffull of servants are chosen based on their appearance and duties, and are assigned to serve the Moon Goddess as personal retainers until more suitable replacements can be found. When coloring, Cutie Mark, and chance coincide, one of the castle's junior stewards is thrust into a role any loyal servant ought to jump at: Lunar Hoofservant. Unfortunately for Nightlight, Princess Luna is far more demanding than her older sister, and being her servant means contending with an unforgiving goddess who demands nothing short of perfection. Furthermore, somepony must be responsible for the inevitable failure. The duty of "Royal Hoofservant" just might be synonymous with "Royal Scapegoat."
Saddled with responsibility far beyond his post and expected to fail, Nightlight has no choice but to quit his post or to become the servant that Luna needs. This is the story of a pony's development from colt to stallion, and from servant to leader.

This story is a sequel to Thrown Abroad

After the events of Thrown Abroad, Suncloak the changeling is happily living in Ponyville. Well, sort of. He needs the love of friendship to stay alive! Luckily, there's plenty of ponies who would want to be friends with him. But let's not forget about other changelings here...

You know, this would be a lot easier if the whole concept of friendship wasn't so needlessly difficult.

Luna's isolation and difficult reentry into Equestrian life has left her without the confidence to communicate with the ponies around her. Especially the one pony she most wants to talk to. Celestia is angry, Twilight is upset and it's all her fault. Then she has an idea... She'll invite Twilight into her dreams. What could possibly go wrong?
