Author's note: this story is still undergoing occasional editing as I figure out what the hay I'm doing. Some scenes may be added, modified, or removed.

Two months ago, a changeling posing as Rainbow Dash tried to abduct Twilight. Nopony was hurt, but Twilight became a bit paranoid--how could she make sure something like that wouldn't happen again? The best thing she could think of was to invent a spell, empowered with her full might as princess, that would forcibly remove the disguise of any changeling in the vicinity.

It's testing day, and Ponyville's about to get twenty percent buggier . . .

AU taking place between seasons 3 and 4. Trigger warning for one scene of implied dubcon.

Beige Beaker is a chemist with a promising career ahead of her. She's got a loving husband, a beautiful daughter, and a loyal best friend. Yes, life is good, and Beige knows it.

Then there's the 'accident.' It wasn't an accident, Beige knows that, but how else can she explain what happened? Suddenly, life has gotten harder, and it's getting worse. And worse. And worse. None of it makes sense. Bad things don't happen this quickly without explanation.

Is it bad luck... or is it a curse?

Set early in Season 1.

A big thanks to my ever-patient (even when I wasn't) pre-readers and editors: Georg, BlazzingInferno, and Pascoite. You guys are awesome.

Princess Twilight has just ascended to her throne of friendship and is prepared to tackle her new duties, but Princess Celestia has something of grave importance for her to do first.

She wants her to meet her family.

Twilight had planned to visit Sunset Shimmer and her friends over in the other world for a nice, quiet weekend, away from all the worries and problems associated with being a Princess of Equestria. Unfortunately, things rarely go as planned.

After an accident cuts her off from Equestria, Twilight finds herself stuck in the human world until the gateway between the two worlds can be fixed. Which wouldn't normally be a problem...

...If she wasn't still a pony.

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

This story is a direct sequel to Princess Celestia: The Changeling Queen. Reading that first is necessary to understand any part of this story.

Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Every week, Equestria's princesses take a break from ruling their kingdom and discuss life. Usually over coffee.

Here are their assorted conversations.

Cover art by Grennadder. The story is marked complete because it's not a writing priority of mine, more a palette cleanser I come back to between harder projects

After the Friendship Games, Sunset feels it's time to return home.

Only when she gets there, Twilight's castle is nowhere to be found, Cadance just got her horn, and Princess Celestia is still calling the bacon-haired pony her prized student rather than a failed one. And just reliving her past isn't on the table thanks to a pair of wings Sunset seems to have sprouted upon her return to Equestria.

With Sunset being back before she's supposed to, will the world stay as harmonious and on track, or will everything go down in flames as Sunset has to deal with allegations that she's really a changeling in disguise, a nerdy stallion with blue hair that wants to be her coltfriend, a pretty pink princess in need of remedial magic lessons, and an annoying purple pre-teen pony that will absolutely not go to bed without first being read Starswirl's Complete Mystical Mysteries Compendium?

Only time will tell

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.

Idol Hooves holds a special place in Equestria. He's probably the only exiled changeling to serve in the Royal Guard, or at least, that's what he expects, as exiles don't really broadcast that fact. However, it's well known that Princess Celestia loves all of her little ponies, and her guards perhaps more so, and that makes it one of the best ways for a changeling to discreetly feed.

But how does a changeling even get there, let alone get exiled in the first place? For that matter, why would it ever go to Canterlot? Set a number of years before the series proper, before Luna’s redemption, Idol details how he was exiled, the ponies he’s met, and the series of misadventures that led him to joining the Royal Guard, and should continue a good ways into the series, as something of an alternate perspective.

Soon, he’ll have to deal with a boisterous new princess to serve and a royal wedding in the works bringing a third to power. Will his old instincts bring this new life crashing down around him? What precipitates Chrysalis’s ill-fated assault on Canterlot? Is it really so wrong for a changeling to enjoy good craftsmanship to an obsessive degree?
