Celestia has held off telling Twilight Sparkle about her immortal biology for years.

And now that she's told her successor about it... she'll wish she hadn't.

Special thanks to Toriandthehorse, for being a wonderful proofreader, editor, and friend.

Now with a Russian Translation by Nogood (who despite the name, is a good pony).

Now with a Korean Translation by B1ackSteel! Thank you again!

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 Dear Princess Sunbutt

When Anon takes the liberty to inject his particular brand of humor into Twilight's friendship lessons, Celestia feels the need to respond, more often than not.

A somewhat unofficial sisterfic to 2Merr's Dear Princess Sunbutt

There may not be a response to every letter, and letters 1-11 were taken from my comments in said sister-story.

Please support 2Merr's story too if you like this one. This is written with encouragement of the original author.

EDIT: Apparently someone's done a reading of this and its sisterfic over on Youtube! Why does nopony tell me these things.

Anon takes over Spike’s job of transcribing Twilight’s friendship reports. He does exactly what you’d expect.
