Twilight Sparkle discovers that the alternate timelines created by Starlight Glimmer in her misguided attempt at revenge did not, in fact, disappear when the original timeline was restored. Instead, they persisted as separate, parallel universes.

Never one to leave a job unfinished, she decides to employ the magic of friendship to restore those universes to a more harmonious state.

She begins with Nightmare Moon.

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."

This story is a sequel to If You Came to Conquer

Princess Nightmare Moon had tried to keep it secret. She had suppressed her power, feigned ignorance, played the outdated fool at every opportunity. She should have known that something like this would happen. A threat that would reveal her, whether she played dumb or not.

If she had to reveal herself, then at least she could protect Equestria in the process. She nocked the arrow. The bow felt so flimsy, but she could not risk him absorbing a spell. She laced magic across the arrow and the string and the air, enough to make it fly faster and aim smoother. She sighted him easily; Tirek was a large target. Now he only had to turn around. An arrow to the spine would kill him simply and instantly, no matter how much magic he had absorbed.

Once he was dead, the hard part would come: explaining herself to Celestia.

Nightmare Moon won. She defeated Celestia, broke the Elements, banished the sun. This all happened a very long time ago. So long ago, that she has had plenty of time to change her mind.

Of course, fixing our mistakes is never so simple, and never without consequences. Even with particularly potent help.

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.

This story is a sequel to The Changeling of the Guard

This is a collection of various stories, short and otherwise, to go along with The Changeling of the Guard.

They aren't absolutely necessary, but the intention is to provide some background or additional material. Things like Topaz's research notes on Changelings, stories involving the other characters, and various insane things Idol has done that don't quite fit into the main plot. They might be chipper, they might be sad, but they're all canon to the main fic... or to whoever from the story is relating them.

Chapter 1 is the Nurse, mentioned briefly in Moonlighting, who brought Idol the Nymph.

There comes a point when you can no longer run from the things you've done. Ryan Williams believes that he has reached this point, but sometimes, just as we are about to close one door, another opens before us, changing our lives in ways we could never have imagined.
