This story is a sequel to Twilight Sparkle And the Very Confusing Day

There were a few loose ends after Discord, who had turned into Eris, had gone into season and turned the entire world upside down in order to create enough chaos for favourable draconequus breeding conditions. Celestia had released the Flutterbeast upon Eris, restoring order and gender normality all over the globe.

Except not everypony and everybody changed back. Males who became mares and became pregnant, stayed mares, Eris' final parting gift of confusion and chaos in the world.

Both of the sexes are now so much more aware of each other's needs following the events of the Great Swap, and Eris' chaos had the unintentional side effect of creating a new level of harmony in the world, as suddenly everypony and everybody now had first hoof (or firsthand) experience in being the opposite sex.

Eris going into season also created the ideal conditions for the apocalypse.

Now with 23% more sequel!

Twilight and her friends all get together for a sleepover, looking forward to some well deserved downtime. Discord arrives, standing outside in the rain, pleading for entrance and to come in out of the weather. Twilight Sparkle insists that this is a mares only sleepover, so Discord does the only thing he can do, doing the unthinkable to gain entry.

Once inside, Discord, now Eris, tries to bond with the mane six and learn the magic of friendship.

The mane six fail to take into account the magic of Discord.

This story is a sequel to Twilight's Escort Service

Ratchette runs a one-pony fix-it shop for enchanted conveniences and devices, the only such facility in Ponyville. Some of her services are limited ones, and there are things she has to refer elsewhere -- but on the whole, she puts the majority of the repair traffic in order and in the two years since she first moved to the settled zone, Ponyville's become used to her. But strangers in town can still have a little trouble with her qualifications. Because her mark says she's perfectly suited for her occupation --

-- while her body claims exactly the opposite.

(Part of the Triptych Continuum, which has its own TVTropes page and FIMFiction group: new members and trope edits are welcome. While this story is technically a sequel, the earlier one just has the main character's first appearance, and this piece can be read as a stand-alone.)

Now with author Patreon and Ko-Fi pages.

After a spell changes your gender, you have to learn how to cope with the sudden changes, but at least you don't have to do it alone.

No seriously, this person helped me out so much! Go thank them!

Midnight Storm has had a hard life. She's wandered from city to city for the past three years, and they've all eventually run her out after they've found out what she is. Against her better judgement, she's placed her last hopes on the small town of Ponyville.

The residents here are nice enough, but when they find out what she really is, will they accept her, or drive her out like all the others? And when Celestia finds out about her, what plans does the Princess of the Sun have in store for the mare?

Story now included in The Goodfic Bin

Morning Breeze. A mare in the esteemed royal guard. Certainly not a rarity, but still it's an accomplishment nonetheless. She has served the night guard to the best of her ability, and though never personally standing guard around her princess, she takes great pride in her duty. So when she learns that she is to be reassigned to make way for the return of the Lunar guard, naturally, she is a bit upset. Especially considering the Lunar guard is made up of thestrals, bat ponies of ancient times that disappeared after the fall of Nightmare Moon. Her irritation at being replaced by, thestrals, of all creatures, has her frustrated. But a chance encounter in the halls of Canterlot castle may reveal more than what she perceives.

What sort of mare would turn down the chance to help a friend? Twilight's been there for me so many times in the past, but now she's a princess with all the new obligations and duties that come with that. The transition... hasn't been an entirely smooth one. Who better to lend her a helping hoof and show her how one deals with nobles, courts, and politics than moi?

I only hope it doesn't end up costing one of us our sanity along the way.

Twilight looked over to her dear mentor, Princess Celestia, and found she had once again fallen asleep mid-lesson. Her intense debate on awakening the princess was cut short when the decision was taken out of her hooves.

“Huh? Oh. Twilight, I am so sorry for falling asleep again. I think we need to reschedule this for tomorrow morning.”

Twilight nodded. After all, Princess Celestia was obviously overworked. If only there was something she could do to help.

Filthy Rich has a problem. His daughter, Diamond Tiara, keeps breaking her promises to treat her classmates with more respect. In fact, she doesn't even seem to really understand what a promise is. Since punishing her does not seem to have much effect, Mr Rich is forced to consider a more creative parenting method. But how can he make such a spoiled, materialistic little filly as Diamond Tiara see the value of a promise?

With money, of course!
