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 sequel to Earth Ponies Are Overpowered

As Twilight works to improve her life infusion treatment, Maud stops by to offer her expertise. There's just one problem: Maud isn't as thrilled as Twilight and her friends about using earth pony magic to make everyone immortal.

Daybreaker: the monster in Celestia's heart, and the age-long mystery of her life. Her friend and tormentor, her companion and foe. Fanatically devoted to their future, yet desiring one horrific to Celestia.

It is growing stronger.

My name is Twilight Sprinkle, and my passion is donuts—from the delicate morsels I serve at elegant cocktail parties to the hearty pastries enjoyed by hard-working ponies who get up early. I don’t have friends, I don’t have books, and I sure as the sun don’t have any wings. I don’t care whether you’re here for revenge, for romance, or for a favor. My name is Twilight Sprinkle and I’m not who you think I am, so either buy a donut or get the hay out of my store!

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 The Luna Cypher

Twilight sets out to learn more of the ways of the world, and soon decides that the whole planet is disorganized, insanely dangerous, and desperately needs to be fixed. And she's just the mare to do it... with a little help from her friends.

Also, there are sky-pirates!

Almost a year after what seemed to be the concluding battle in Celestia's great crusade against necromancers, something Mortem believes to be borderline discrimination, he discovers one of Celestia's armies setting up camp just outside his stronghold.

Not wanting to jump to any conclusions or risk angering the very powerful Princess, he concludes a diplomatic solution would be the best way forward. And so, he writes a letter.
