Although Canterlot was saved in the end, there was still damage.
Although they celebrated their victory, there was still loss.
Although they said "sorry", there was still resentment.

But not from the pony you expect.

A rebellion formed outside of Celestia's castle, declaring Twilight Sparkle and Cadance to be their new Princesses after she and Luna failed to protect Canterlot from the Changelings. Leading the rebellion is, to the shock and surprise of Twilight and her friends, the mysterious Mare Do Well, who claims to be the "will of the ponies’ voice". After discrediting Celestia, she proceeds to accuse Twilight's friends of "betraying their Element" and has them seized to be interrogated.

With Celestia gone to reflect on the damages she had done, Twilight Sparkle must find a way to restore the denizens of Canterlot's faith in Celestia, save her friends, and disband Mare Do Well's rebellion. However, a question still lingers in her head. A question that Mare Do Well presented to her. Is there a pony in her life that she can’t forgive?

Twilight is more than thrilled when Princess Celestia herself summons her to Trottingham to start a weeklong vacation just between the two of them. When both Princesses stumble upon a familiar Ponyville native, Twilight finds his strange actions suspicious. Especially when Celestia swears he's someone else. Someone way older than she thought.

Extra Extra Side Note: Cover art done by me

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.
