When the Cutie Mark Crusaders dig up an ancient magical artifact, they unleash a spell on the town that allows everypony to see a "lie meter" floating above each other's heads. While attempting to solve the mystery, Twilight Sparkle has to analyze the tenuous balance between friendship and honesty. She doesn't like what she finds.

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.

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?

"Oh come on, Applejack! Just one trip around the clouds! One!"

It's an invitation that Applejack has heard countless times. However, no matter how often Rainbow Dash bugs her to experience an air ride, the farm filly flat out refuses.

Then one afternoon, on a day when Applejack is strangely quiet and distant, she suddenly agrees to Rainbow Dash's persistent request. The pegasus happily oblidges, not knowing what has truly motivated Applejack to give in, nor the fact that--more than anything--Applejack could really use a good friend right about now.

Twilight Sparkle comes across a small, battered diary detailing a new form of transportation. While the research is sloppy and the notes incomplete, Twilight takes it upon herself to see that the ancient project is completed.

Of course, nopony said it would be easy.

He guarded this city almost all of his life, which ended the same way his father's did - by sacrificing himself to protect everyone. Having said farewell to his beloved sister, he was about to move on, but not before splitting a fragment of his soul, creating another Soul Dew in the place of his father's destroyed one, so that part of him could continue to protect what mattered to him most: his sister, and the city. What he didn't know, however, was that this process could lead to... unexpected results.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
