This story is a sequel to Outwitted by a Polychromatic Cube

Rainbow Dash, Ponyville's one and only stunt devil extraordinaire, has been an avid reader since injuring her wing and taken a dive into the world of literature to pass time while her wounds healed. But the problem is that she's too afraid to venture outside the famous Daring Do series and is stubborn towards friend's attempts to convince her to try something else. What will it take for the athletic pegasus pony to try something new?

Celestia discovers a lingering trace of Nightmare Moon's soul still lodged in Twilight's mind—a survivor of the lingering effects of the Element's magic.

Faced with the threat of gradually losing her friend to Nightmare Moon's evil influence, Celestia realizes the only way to save Twilight is to let the storm of dark magic take its course all at once.

And yet, as Nightmare Moon's corrupting magic tears away at Twilight's forgiveness and understanding, and Twilight begins dredging up unexpressed doubts once kept controlled, Celestia must face a lifetime of confrontation her student has kept covered.

It is going to be a long night for both alicorns.

This story was written for the Tenth Bimonthly Twilestia Contest. It placed somewhere.

Rainbow Dash is a headstrong, athletic pony who is utterly faithful to her friends and doesn't keep any secrets from them. Or so she pretends. Yet a surprise visit from Twilight Sparkle is about to blow the secret wide open, and the multi-hued pegasus will find out just how strong their friendship is.

Note: This story was written in the week following the airing of "May The Best Pet Win", and well before "Read It and Weep" was even known about. As such it haws since been overtaken by canon, but most folk tend to like it still so I will upload it here so I have a bit of a presence on FIMfiction beyond "lurker #347,921".

This story also includes "The Unrelated Epilogue" which is a mini-story based on a loose bit in the main one that I felt did not stand on its own, but that I wanted up nonetheless. It has Luna, but not RD or TS.

Twilight Sparkle has been stuck on Earth, as a human, for a while now. It wasn’t planned, but the human girl that she stays with is at least very helpful. When the stress of finding a way home gets too much for a stranded Twilight Sparkle, her friends look for a way to keep her from going crazy. A few video games won't hurt, will they?

A side story of Merlos the Mad's A Twilight Landing. It takes place just after chapter twenty-four. If you read this story by itself, most of the jokes will still make sense. This may also be considered canon.

I have been informed, that the cover Merlos found for this, is art by MegaSweet!

In a world where ponies see in grayscale until they meet their soulmates, finding your soulmate is a momentous occasion, where the special connection between you quite literally colors your life. When Twilight began dating Rarity, she didn't mind that she couldn't see in colors.

Or, so she thought, until the day Rarity suddenly could.

RariTwi Challenge fic meant to be a different take on one of the many Soulmate!AU prompts circulating Tumblr.
