This story is a sequel to Winds of Change

Changelings have always been a secretive race, shrouded in mystery and keeping to themselves, staying unnoticed and in the shadows, feeding where they could and avoiding discovery at all costs. When Chrysalis made peace with Celestia, the veil of secrecy and subterfuge was shattered, and thanks to Twilight's efforts, the other changeling queens can no longer remain hidden.

Of course, Twilight is more than happy to leave the tricky diplomacy to Celestia. She's having a hard enough time dealing with her own amorous changeling queen and her new personal pegasus guard competing with her.

Failing once in her attempt to take Canterlot and failing again in her attempt to take down Twilight, one would think Chrysalis would have cut her losses and let things be, but the queen has once again appeared, this time in broad daylight with no disguise and no army. Her weapon of choice? Diplomacy.

Now Twilight is having to deal with the changeling queen, but surely putting up with her antics will be worth the knowledge she's willing to provide about her mysterious race and the potential undiscovered agents still within their midst...right?

Takes place before Magical Mystery Cure and diverges from there.

After ascending to Princesshood, Twilight decides that it's time to really take the notion of "A Sound Mind in a Sound Body" to heart. She has the "Sound Mind" bit down (mostly), but years of sitting inside hunched over a book has given her quite a bit of ground to make up on the "Sound Body" front.

Fortunately, she has an athletic friend to help her out.

Equestria is an old nation, and one that has had the luxury of the same, immortal, regime for centuries. While this has given them unprecedent stability, especially in a land that seeks to throw a world-ending threat at them every other Tuesday, it does come with a tendency for the rulers to not so much repeal laws as just ignore them and act as if they've been done away with already.

Most of the time, this works out just fine. Until another immortal--such as, say, a starving royal changeling looking for somepony to help her regain her strength--remembers these laws and invokes them to use to their own advantage. By arriving at Twilight Sparkle's castle and declaring herself a member of Twilight's royal harem.

And she's just the first.

-----
K'larra was a deep cover changeling sent to spy on Ponyville in preparation for the invasion. Sazzix was a survivor of the invasion that slipped past the wards and posed as an ordinary pony.

They fell in love.

Then they figured out they were both changelings.

Then they got drunk.

In the midst of another conflict with the Changeling Queen, fighting over the next macguffin with the potential to change the fate of the entire world, Twilight decides to propose a challenge of sort to Chrysalis.

Twilight believes that it is possible for Chrysalis to have a normal life, a good life, one where she doesn't have to worry about the hunger that have cost her so much, all without needing to change (too much) who she is.

Chrysalis is, understandably, skeptical about that, but nevertheless she take the challenge, even if it's just to prove how wrong Twilight is.

But... would it be that bad if Twilight was right? After all, a good life, a life without hunger, does sounds nice. But is that what Chrysalis truly wants? Would she be okay with just that? How much would she be willing to change for a good life? And at what point would she had changed so much that she has stopped being herself and has become someone completely different? Would she even be herself at that moment?

These are the questions that Chrysalis will have to face to obtain her answer.

This story is a sequel to Tantabus Communication Protocol

What started with laziness and a tiny slip-up in arcane intelligence creation has blossomed into its own being. With Luna's blessing, the second Tantabus is free to flit around the dreamscape as it pleases, unburdened by oversight. And what pleases it is making good dreams. Who couldn't be happy by making others happy?

As the Tantabus settles into its life, its horizons keep expanding, forever revealing more of the world and of ponies. There's always new things to learn. New dreams to spice up. New nightmares to beat down. New ponies to help. New ponies to annoy.

Don't tell Luna about that last part.

This story is a sequel to Aunthood Issues

Pop-cultural investigative reporter Coranto has heard some pretty out-there excuses for rumors. Some were even true. But when castle gossip says Luna has had a baby, and she claims she's created an entity to patrol dreams called the Tantabus, Coranto knows she's smelling a load of hogwash. The idea is absurd. Patently. Never one to let the truth hide, Coranto decides she will get to the bottom of these rumors, and nothing will dissuade her. Not anything Luna says. Not even the Tantabus itself taking an interest in her crusade.

...Wait...

This story is a sequel to Tantabus, Mk. II

The new and improved Tantabus has behaved itself thus far, but Luna has delayed telling Celestia about it. Until one night when it jumps into Celestia's dreams to say hi and inadvertently reveals itself. Luna must now introduce Celestia to her little bundle of self-aware psychic dream energy sooner than she imagined.

Trying to patrol the dreams of every pony in Equestria can be stressful. To ease her burden, Luna retools the Tantabus to turn nightmares into good dreams instead of vice versa. Aware of her mistakes from last time, she tests it out thoroughly, making sure there are no unexpected behaviors. And as far as she can tell, there are none.

Except that it's started calling her "Mom".

Faced with the prospect of possibly creating life, Luna seeks out Twilight's advice and assistance. With a little luck, they can get this all sorted out before the sun rises.
