One fine morning, Spike woke up early and ran some errands. Then he found Discord putting up a seller's stand, apparently ready to open his own business. One which offers a one-day transformation into anything the user wants. And he apparently had the patience to set up his shop LEGALLY. Twilight and the others brace themselves for the inevitable...

This story is a sequel to Ageless, or Celestia Plays Dice With the Universe

Twilight learned she was ageless a few weeks ago. She also started dating Celestia a few weeks ago. Life moves swiftly, even for the long-lasting and the long-suffering. There are a lot of things that Twilight will have to adjust to. Dating Celestia may be the easiest of those things to accept.

Editing/Pre-reading done by the ineffably gracious and generous TheMaskedFerret and oftentimes by the lovely, beautiful, and brilliant ScarletWeather, whom I love with all my heart.

Ember's been the Dragon Lord for a few months now, and the pressures of the throne are beginning to get to her. Although she told her new (and only) pony friend Twilight that she could write to her with any questions about dragon culture, she was beginning to think that maybe she would need to send a letter the other way. After all, Ember's a young princess, just like Twilight! Surely she can give her some princess-ly advice? But Twilight may find that a dragon princess has a few problems that might be a bit different from her own.

*Mods, Ember character tag pls.

This story is a sequel to The Most Powerful Dragon in Equestria Visits for Tea

Ember is back, and she's more sarcastic and adolescent-minded than ever. She's returned to the dragon lands; older, wiser, and more understanding of ponies. That's when somepony tries to kill her.

Rated T for language and suggestive themes. Cover image by Léa Imalou.

Twilight just wants to sleep; unfortunately for her, not only is Celestia in a playful mood, but Luna is itching for some quality time. Shining Armor and Cadence then show up, and it turns into tug of war with Twilight as the rope. The prize? Spending quality time with everypony's favorite purple alicorn.

This story has Twilight/Celestia and implied Twilight/Luna. Also, Cadence has a very... vivid imagination.

Now a plotless(okay, so there's a bit of plot. Just a smidge, though.) ball of comedic fluff with multiple chapters.

Chapters currently edited:
Chapter 1 - Say It - edited by ultra1437

A collection of short, random stories. Most of these were comic ideas that, for various reasons, I've decided not to make into comics, but the idea was too good to just abandon.

A Real Princess: The ending to A Canterlot Wedding, re-imagined with Cadance acting more like a real-life princess rather than a perfect magical pony princess.

Sniper: Celestia raises the sun at the Summer Sun Festival, unaware of the pony standing on a distant rooftop...

Flutterdrunk: Twilight discovers the consequences of getting Fluttershy drunk.

A Night With the Moon: Nightmare Moon turns out to be more prepared for the Mane Six's attempt to retrieve the Elements than Twilight had though. Twilight is not prepared for what happens next.

Fish Food: Sunset Shimmer enacts her terrible revenge upon the Sirens.

Edit 11/28/15: Aaaaand I'm now out of character slots to add. I threw the 'other' tag on there, but just assume it's every character ever.

After Twilight and her friends rediscover Starswirl’s last spell in the ruins of Golden Oaks Library Rainbow Dash asks, ‘why can’t we all become alicorns?’ Now Ponyville is host to five brand new alicorns and the girls have everything they could ever want; magic, flight, power, influence and all of Equestria wide-open before them... but being a Princess is far more than just having wings and a horn.

With thanks to Luna-tic Scientist, Lord of Dorkness, docontra, and JCatt for their help pre-reading. Cover image by Pixel-Prism.

This story is a sequel to Mechanical Aptitude

Six Elements of Harmony.

One hundred and eighteen Elements of the Periodic Table.

Let's see who blinks first.

(A collection of irregular short pieces focused on the ponies (and sundry) of Equestria dealing with the other fundamental building blocks of the universe -- more or less. Most of them will be part of the Triptych Continuum, which has its own TVTropes page, FIMFiction group, and a newborn character page: new members and trope edits are welcome. However, these can be read as standalones, and no knowledge of the others is required.)

Now with author Patreon and Ko-Fi pages.

Open Concept: any author who wants to write and post a TEoE story themselves has my express permission to go for it.

This story is a sequel to Families

Third in the Nuptialverse...

Twilight Sparkle has done much for Equestria. If it weren't for her, Equestria would be destroyed three times over by now.

So what happens when she has to leave? What happens when she and Spike are forced to depart from Equestria in order to fulfill their duties? And what happens when there's still important things at home to do?

Applejack, Rarity, Pinkie Pie, Fluttershy, and Rainbow Dash now have to get along without the one who leads them. All of Equestria is counting on them. Can they do it?

AU only post-season 2, since the basic idea for this fic was created long before it aired. Events similar to season 3 have happened, all of which will be revealed. Strongly recommended you read Post Nuptials and Families first.

Cover art by Concier

In the wake of Tirek's attack on Equestria, the last thing the princesses could have expected was a broken and exhausted Chrysalis appearing in Canterlot seeking their help — except for her connections to Luna's past and Twilight's ascension.
