Non-canon prequel to The Enchanted Library

As a filly, Rarity's favorite bedtime story was about three princesses trapped throughout Equestria by a wicked spirit of chaos. How she dreamed of finding them all when she was older, especially the princess trapped in a library under a tree. She knew, however, that fairy tales weren't real.

Only when she grew up would she find out how very wrong she was.

Based on an AU a friend came up with in which Rarity stumbles across an enchanted library where Twilight is its spiritual guardian, and both form an unlikely friendship as she helps Twilight be restored to normal.

Princess Celestia always thought she knew how her kingdom worked. The Unicorns used magic specialized to their jobs. Pegasi flew in the sky and handled the weather. And Earth ponies... Earth ponies... uhhmmm...
Huh. Maybe Princess Celestia didn't know everything about her ponies after all.
Princess Celestia realized this after Applejack came to speak with her about a tax unfair to Earth pony farmers. It was during their conversation that Celestia realized she needed help.
Huh, isn't that odd Princess Celestia has had to leave on emergency business, leaving Luna to raise and set the sun? And hey, is that a new pony living and working at Sweet Apple Acres? I think her name is Sunshine Meadow. Surely, it's just a coincidence. Surely.

Twilight Sparkle has been keeping Spike up at night with obsessive writing. One night, Spike's curiosity gets the best of him, and he discovers Twilight has been writing bad shipfiction about herself and her friends.

He decides to teach her a lesson she'll never forget.

After another stunt gone wrong, Rainbow finds herself cooped up in a hospital room again. But when she ends up getting roomed with a nine-year-old colt, her stay at Ponyville General takes a turn that's worth just a little more than reading a book about an archaeologist.

Rainbow Dash notices something wrong with Pinkie Pie. What does it mean that her Pinkie Sense has stopped working? Twilight's tests make her violently ill, and reveal a shocking truth...

Already taken aback by the stark contrast from Pinkie Pie, Rainbow Dash discovers something mind-blowing after challenging Maud to a rock throwing contest.

Surely a pony who doesn't like winning couldn't exist...

Right?

Perhaps there is a lesson to be learned here.

Twilight Sparkle, Arcane Mage, knows that there is some truth to the story of Nightmare Moon, but her mentor, Princess Celestia, dismisses the matter in a heartbeat. She sends Twilight to the town of Magiville to oversee preparations for the Summer Sun Celebration, much to Twilight's distaste.
Unbeknownst to her, the darkness is gathering in Mystica. Assassins lurk in the shadows, Undead gather in the forest, werewolves sharpen their claws, and criminals and mercenaries prepare themselves.
To win the coming battle, Twilight will have to rely on her wits, her magic, and the five mages she's been saddled with. No matter how much they annoy her.
Rated teen for violence and language. Humanized, action-y. Based on the first two episodes, with some large changes made.
