After the disastrous invasion of Canterlot, an injured changeling wakes up near a small cottage and is quickly discovered by two of the last ponies she ever wanted to see. Now, with the help of her new "friends," she has to remain undetected in a town high on changeling hysteria that would not hesitate to throw her in the Canterlot dungeons should her true nature be revealed.

Simple, right?

Too bad she couldn't have picked a worse form to stay inconspicuous...

The newly coronated Princess Twilight suffers an abrupt tragedy. Having lost two loved ones, she begins to question her own mortality, and that of her friends.

AJ, Dash, Rarity, Pinkie, Fluttershy. . . they are just the beginning. Twilight will live for thousands of years, so every pony she cares about—every pony she will ever care about, will die.

She could barely handle the pain of one funeral, let alone the thought of hundreds of them. Twilight finds a clever way to ensure all of her friends never die. They can’t all be ageless alicorns, but they can all move into Twilight’s Dollhouse. Then they can be best friends forever.

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 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.

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.

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.
