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.

Mole Cricket, a changeling, faces the greatest challenge of his life so far: Convincing all four princesses that he deserves a chance at earning citizenship in Equestria. Can he convince Twilight Sparkle, Celestia, Luna, and Cadance that he can be a contributing member to society?

An Interquel to the story "Your Fangs Are Showing", this takes place between chapters 3 and 4.

An unexpected encounter with a stallion helps Fluttershy feel better about a personal problem... And then hilarity ensues.

There is now an Interquel in progress, taking place between chapters 3 and 4. And there is a sequel planned.

Rated (R) for Reboot.

Sequel to Transcend

Raindrop needs the scattered Elements of Harmony to fix her changeling heritage. But the search will require a journey that the young pegasus might not be ready for.

At first, Chrysalis loathed him; the dumb-as-a-brick woodspony who goes by the name of Evergreen. But through circumstance, he is her only savior. And slowly, she comes to love the simple pony and his way of life. But her life as a changeling keeps holding her back. Will there be a happily ever after for them? Or are they doomed for failure?
