Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

As Twilight goes throughout her new life, she takes care to never forget the special ponies that helped to mold her into who she is, even with the pain that comes with the remembrance. One pony in particular, however, stands out among the rest.

When an unknown future beckons, she calls upon the blissful memories that she treasures so much, and remembers the pony who taught her the most important lesson of all...

How to love.

Thanks for everything guys. I never expected this thing to get so popular. I need to rework the second chapter, but it looks like there's going to be a blue moon every Friday for a while yet. Thanks again for your support and please keep reading and reviewing!

EDIT2: I've updated the character list again, a little preview of the second story arc...

EDIT 3: Just doing a quick character update to account for changes made to the next Arc...

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 The Retribution of Chrysalis

Queen Chrysalis has spent the last few weeks living with Twilight Sparkle, hiding from the public eye and awaiting news of Princess Celestia's changeling relief effort. When Shining Armor discovers a critically injured changeling on the outskirts of Appleloosa, to Chrysalis' infinite delight, her hope for her race's survival is instantly reinvigorated.

But then the Canterlot hospital refuses to properly care for the changeling, leaving Cadance to provide the love he requires. The publicity forces Chrysalis to reveal herself to a fearful populace, driving her into the hooves of a fellow outcast. And perhaps worst of all, the awakened changeling has forsaken his queen. In his eyes, and in those of all of Equestria, Chrysalis must once again redeem herself.

With the population of the changeling race crippled by their expulsion from Canterlot, and their queen powerless to salvage it on her own, Chrysalis requires outside help from Equestria to get them back on their feet. But reaching out to Princess Celestia proves troublesome, as she cannot risk returning to Canterlot, and the one pony outside the city with a direct line to her is also the least willing to trust her. The salvation of her kingdom may rely on her making amends... and perhaps making friends as well.

Now has a sequel!

Being in a position of power is never easy, especially if you are the only ruler. Queen Chrysalis discovers this as the broken remnants her subjects begin to wither away without any love to properly sustain them, grieving over their fellow changelings who did not survive the trip home. Their population continues to plummet, and she is left with only one option.
