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.

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.

Princess Luna created me in order to make sure she never would forget the pain she caused Equestria.

But this? This is not the way to accomplish my directive.

If only I could let her know...

Princess Luna ordered the Tantabus to torture her dreams every night so that she would never consider returning to the dark path she once trod as Nightmare Moon.

Luna should have remembered just how difficult it was for her to obey rules before she used her own essence to create what was, in effect, a smaller, more headstrong version of herself.

The Tantabus is determined to follow the true purpose of her command, no matter the consequences, large or small.

Or very, very small.

What goes through the mind of a nightmare?

How does it view the world?

How could it justify its rampage?

Injured, broken, and nearly powerless after Luna learned to accept her own mistakes, the Tantabus was presumed long gone. But the truth is that it lives on, trying to lead a normal life under 'her' adoptave father, Jake. Stranger still is that not everypony can see her, and she feels oddly weak when nopony else is around...

Ever since Luna returned from her banishment and been cleansed by the Elements of Harmony, she has always been worried that she would turn back into Nightmare Moon. So without telling anypony she made a magical construct, named the Tantabus, that would plague her with dreams and nightmares of what would happen if she did turn.

That is until one night the Tantabus did something that Luna never thought would happen, it gave her a good dream.

How long has Princess Luna been alive? It was a question that even the princess in question can't answer completely. It's not her fault. When you become an immortal goddess, time practically loses all meaning and the years fly by in the blink of an eye. It was hard to remember exactly what happened when or who did what at a certain point. It was hard to even remember her own birthday. It's a good thing her daughters were there to remind her.
