When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

Not everything is as it seems when Dinky visits her mother in the hospital.

Twilight Sparkle presents a collection of interviews, letters, essays, poetry and prose compiled over several years of her relationship with the human Bellerophon and his "herd", covering subjects as broad as Equestrian social taboos, comparisons of earth and Equestrian mythology, romance and the occasional recipe. Compiled by Twilight Sparkle, with foreword by Her Royal Highness, Princess Celestia.

(This is a bit of an experiment based on the worldbuilding concepts presented in AnonAuthor's Xenophilia [[NSFW] - caveat lector!], which intrigued me enough to want to take a closer look. It's likely you'll be very confused by this unless you read at least some of Xenophilia. Updates will appear as and when an idea pops into my head for a thing to add. And fair warning, some of this might come across very dry and dusty. Thank you academia! And thank you AnonAuthor for letting me have a go, and both AnonAuthor and AnonponyDASHIE for all the collab work they're doing. I'll make up for the dust by tossing in the odd piece of art now and then.)

Rarity and Fluttershy have been friends for years, and every week they go to the spa. But after every trip, Rarity finds herself growing greener with envy over Fluttershy's beauty and grace, if not something more than just envy— and what might happen if she finds out Fluttershy feels the same way about her?

Nopony ever said the friendship between Fluttershy and Discord would be an easy one. The difference in their life expectancies doesn’t help, but that’s a problem Discord can fix with a snap of the talons—that is, until Fluttershy finds out. Discord isn’t one to give up easily, though. He’ll do anything to keep his one and only friend. Anything.

There is now a video review! And still another video review! And Russian and French translations! And there are dramatic readings from Joehighlord and Dr. Wolf! But wait! There's more: Dr. Wolf has collaborated with Meb90 and a team of other talented artists to produce something amazing.

Something is definitively up around here. Applejack and Fluttershy have been spending a lot of time together without the rest of the gang. Well, Rainbow Dash is on to them! In fact, she is sure this is the no-good friend-stealing Applejack's doing, and she will not stand for this - whatever this is.

Also, Rainbow Dash wears a corn hat.

Bon Bon's voice is funny, and that's about all that anypony who meets her notices, as her marefriend Lyra soon steals the spotlight with her explosive personality, strange obsessions, and curious beliefs. And why not? Bon Bon is, after all, a perfectly ordinary, boring pony in every way but two: her voice, and the carefully kept secret that she isn't really a pony.

Princess Celestia always knew that Twilight Sparkle was destined for great things, but she never revealed the source of that knowledge, not even to those closest to her. When the day of Twilight's true destiny finally arrives, can Celestia fulfill an ancient promise to save Equestia's past, present, and future, even it means saying goodbye to Twilight forever? How can Celestia refuse her mother's last wish?

Celestia dreads 'Drudge Day,' the weekly time she spends dealing with legal affairs. As problems roll in she finds herself melancholy; has she really seen all of this before? Surrounded by a parade of pleading ponies, Celestia begins wonder if immortality is all it's cracked up to be.

Lyra and Bon Bon: foster parents? It'll happen, if they can only get past their sardonic caseworker, nerve-wracking inspections, and each others' neuroses. That's assuming things work out with any one of the children that passes through their home. After all of that, there's just the matter of the adoption and the birth relatives. Hugs, heartbreak, and humor will follow in droves.

Also, Lyra tries to cook soup.
