This story is a sequel to For the Hive

A few months after the events of Queen Twilight Sparkle's reveal that she and her hive can produce love, the changeling hives find themselves in an arms race. As Aegis Altair watches over her queens haggling with the minotaur emperor, she finds something that just might give Phoenix's Roost the edge it needs to come out on top.

This is a short interlude before hive book 3.

This story is a sequel to The Luna Cypher

Also, there are sky-pirates!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Princess Twilight Sparkle discovers a centuries-old mystery hidden in the Royal Archives. Her investigation leads through layer after layer of deception and misdirection, setting her hooves on a path that seems to be leading to a mysterious secret. Along the way, she learns that some friendships can be very, very strange.

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

True friends do everything together, but the night after Princess Twilight’s coronation, the bearers of the Elements of Harmony decided one of those things would be to go out clubbing.

It was a particularly bad idea.

Eleven months later, they find themselves doing yet another thing together which even the best of friends should avoid doing together.

Delivering foals.

My editors (who would like to remain anonymous): Masked Ferret, Tek, Docontra

Warning: Rated T because it contains scenes of childbirth (but not M because it doesn’t show… you know). Although all of you have gone through the process at least once, you may not remember just what was involved. Trust me. It’s both terrifying and worth it.

Picture source: Wiki

A fun, delightful romp in which Twilight learns an important lesson about friendship, harmony, and why cobalt-jacketed atomic weaponry is a bad idea.

(cover fixed, apparently there were some technical difficulties)

For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.

Some beautiful fanart of the end of chapter three was done by Dmann892; you can see it here.

More awesome fanart, this time from chapter one.

Now with a TvTropes page (obligatory TvTropes warning goes here).

If you want a Russian translation, you can find it here.

There is now a reading of the story on Youtube, which starts here.

This story is a sequel to Pandelirium

Things have started to settle down since Twilight Sparkle and Pinkie Pie were crowned as princesses of Equestria, but that doesn't mean that any semblance of normalcy will be arriving. The first major summit of Equestria's ruling princesses is cut short when a thief steals the Element of Magic and escapes to another world. However, because of Pinkie's rather unique skillset, Celestia sends her to retrieve it, rather than Twilight. But even though the other Element-bearers will be staying behind, Pinkie won't have to face this task alone....

This story is a continuation of the plotline begun in The Petriculture Cycle. The first story can be found here.

It has been a year since I last saw her when she appeared on my doorstep, strangeness in her eyes and a mumbling under her voice.

She asked for my help to investigate a peculiar object, which once held an odd ancient magic. But it's benign now, she said.

It's benign now.
