This follows the events described in the Cutie Mark Chronicles, with one small change: The Sonic Rainboom doesn't happen like it was supposed to. Six destinies fail to start. But when one door closes, another one opens.

This is supposed to be close to Canon, but since history is altered and the characters don't experience many of the events that make them who they are in the show I'm listing this as alternate universe (does that make sense?)
For the same reason I'm listing the OC tag, even though the OCs are the mane 6 living different lives.

Nopony dies, nopony suffers permanent psychological scarring, and no irrational whirlwind romances happen.
If I have inadvertently included somepony's OC I apologize.

When Fluttershy received her certification as a fog specialist, she only wanted a plausible excuse to write off the expenses associated with her ground-based house on her taxes. However, when an accident in Cloudsdale sends a blanket of industrial-grade clouds rolling towards Ponyville, Fluttershy suddenly finds herself in charge of coordinating the response, mostly because she's the only fog specialist in the area. Can our heroine step up to the challenge at hoof, or will she risk facing the wrath of the Equestrian Revenue Service?

You'd think life would be all caviar and high society luncheons if you were born into Equestria's wealthy elite. But that might not be the case if you also grew up in Ponyville, if your parents named you "Filthy," and if you had a grandfather who had some very odd notions about how rich ponies are supposed to behave.

This is a story about growing up in the time of Applejack's parents' generation. It's also about the Apple and Rich families, what happened with them, and why Diamond Tiara is such a mean little filly—especially to Apple Bloom. But mostly, this story is about learning to be rich, trying to truly love and be loved, and whether it's really possible to have both in this different take on Ponyville's richest citizen.

Years ago, two unicorn prodigies attended the same school without knowing it. One became changed by friendship at an early age--the other far later in life.

At a fashion show gone wrong, the two prodigies at last meet. Being who they are, it's impossible for them to resist comparing notes...

As the personal protegee of Princess Twilight Sparkle, Luna's life is more than crazy enough for a unicorn of her age. Balancing her studies and putting up with her hard-partying pegasus sister is enough to keep Luna up most nights with little or no social life to speak of. But as the only one who believes the legends that Tirek the Terrible is returning and the only one who actually cares enough to stop him, it doesn't look like Luna is going to be getting any sleep anytime soon.

Which is just as well, because she keeps having the strangest dreams about a life she half-remembers; a life of long nights spent as Princess of the Moon and a terrible catastrophe that befell her kingdom. But those are just dreams...right?

With the fate of Equestria resting on her shoulders, Luna must unite a group of unlikely allies to stop Tirek, save the world, and solve the riddle of her nightmares before they come to life.

WANTED:

The newly crowned Princess Twilight Sparkle has set up a bold new initiative to discover new magic, and is sending out an open call to the unicorns of Equestria to apply for her research team. No experience in magical theory or research necessary. Enthusiasm and out-of-the-box thinking a must. The Equestrian government is not responsible for any physical, emotional, or magical trauma experienced during the course of the project or the application process.

Since the recovery of her crown, Twilight has become obsessed with rediscovering the lost magic which created the 'Portal Mirror': a gateway to another world. On top of that, a former enemy has arrived in Ponyville, looking to make amends.

With her help, Twilight ends up with more than she bargained for when an accident occurs during her studies, touching off an adventure spanning across multiple realities. With a new gateway linked to a myriad of new worlds, what will they find as each expedition brings them one more step removed from the universe they call home?

Taking place a month after the conclusion of "Rainbooms and Royalty," Rainbow Dash is settling into her new life in Ponyville. On the whole, it's great! But as some minor tensions crop up at her job and her new life, an old friend comes into town to turn everything upside down. What's a pony to do?

Waking up in an alternate universe in which you are a supervillain can be hard.

Finding out your friends are rebels trying to kill or overthrow you isn't very easy to deal with either.

But trying to solve the situation? That's a real horn cracker.

On a dark day, one may wonder: just what horrors lie beyond the veil of the heavens? What ghastly demons exist that could only spawn in a pony's dreams? What terror!? What blight in the face of all that is good!? What- wait, it's the Mane Six?

What sort of twisted reality contains a lycan Applejack, a vampiric Fluttershy, a ghostly Rarity, and a lich queen Twilight Sparkle, you may ask? Why, it's just the Nightmare Realm, existing one and a half dimensions below and above the normal Equestria, and they are sick and tired of Nightmare Night not living up to its name in the 'real' world.

However, are these nightmares truly nightmares, or do they just like a good scare? Why, it depends on who you're talking to! So sit tight, give way to fright, for coming soon is Nightmare Night!
