Canterlot has nearly fallen.

My troops now flood the streets.

Victory is all but assured.

So why does Celestia have that stupid smile on her face?

And more importantly, why does she wish to speak with me?

Celestia invites Twilight over to help her plan for the next Grand Galloping Gala.

Twilight raises some questions about Celestia's plans.

It was a bright sunny day when Princess Celestia was taken from us by three very familiar fillies... Or was she?

This story is a sequel to Electra Complex

Shining Armor is awoken by his daughter bearing a surprise for him.

Shining Armor is wary of surprises from his daughter.

Behind Celestia's graceful smile and kind eyes, secrets are hidden with a thousand years of practice. The whispered legends of her depravity hide a dark grain of truth, hidden in the mists of time: the clash with Nightmare Moon left her with scars that will never heal.

This was written before Season 4: it's in a Season 3 universe.
An eighth chapter, by Icebox Froggie, is on its way, and will be added to the story at some point.

The 11th Wonder

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.

Done to go with the episode Do Princesses Dream of Magic Sheep?

Now on Equestria Daily

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...

"Suppose I killed them all?"

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.
