The Everfree forest is just like any other forest—except it's full of monsters and weird magic junk, but ignoring that—it sometimes grows out of control and needs to be trimmed a bit. In order to keep the forest from growing too large, Celestia asks Twilight to start a controlled forest fire to burn a portion of it down. It seems like a simple request, but a series of mishaps and misunderstandings lead to some miscommunication and, subsequently, to Twilight setting fire to all of Equestria.

Starlight Glimmer's attempts to stop the Rainboom pulled Twilight Sparkle into many possible timestreams.

In one, Rarity and Rainbow Dash survived Nightmare Moon's victory over the forces of light, eventually attaining positions of prominence and comfort in the Nightmare's service. But when the unexpected visit of an Alicorn and Dragon sheds light on a growing conspiracy against the wicked mistress of the night, Rarity and Rainbow Dash may yet be inspired to risk what they have gained to join the fight for a better world.

Yet darkness lingers even in the hearts of some who would oppose the Nightmare, and not all agree on what a better world would look like...

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.

Love is one feeling that can never be taken from someone's heart. No matter how many years of separation, no matter what wrongs were done in the past, no matter how much enmity exists between two ponies, love will always stand; at least that's what Nightmare Moon is hoping for. 700 years ago was the last time she had seen her sister Celestia, and her departing words had simply been 'I love you'. Now, after so long, Nightmare Moon's heart longs for its other half; and thus, she has brought Celestia back from the far away, magically void lands she cast her to so long ago. Now, she wonders if her sister will ever find it in her heart to forgive her for what she's done, and if their lives together can ever resume as they once had.

Takes place 300 years before when Luna would have returned from her banishment to the moon, and takes place in a universe where Nightmare Moon was never banished in the first place.
