Mood Wings - Observations on Pegasus Body Language.

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.

Kuno, a young changeling, is left weak, bloodied, and bruised after the events of the Canterlot wedding. She is soon discovered by Warden, a Royal Guard. But for some reason, Warden shows her mercy. Instead of taking her into the custody of the Royal Guard, he becomes both her captor and her savior. But over time, Kuno will come to ask herself the hardest question she has ever pondered: Can a changeling feel love?

==Originally written Fall 2011== Equestria Daily Post==
After a long day of ruling Equestria, the Royal Sisters need a chance to unwind. Luna's solution is a few glasses of her once famous Moonshine, a drink distilled from moonlight. Celestia has been sober for a thousand years, but the temptation to have "just one" glass proves too great. Yet, when that one glass turns into several, it's Twilight who will have to deal with the princesses when they’re drunk off their flanks.

In a world full of magic, mere words can pose a deadly threat. When simply reading a sign can instantly infect the unwary, and cases start to turn up all around Ponyville, Twilight Sparkle casts the only spell she can find that can give her the time she needs to find the cause of the plague. But then she has to figure out how to stop the epidemic... without being able to read.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

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.

Novel Tale is an author that's been living in Canterlot for about ten years now. That's a pretty good track record for a changeling. He's even included a changeling character in his latest book, and his fans have been loving his take on such an obscure mythological creature, especially his biggest fan, Twilight Sparkle. Things are looking up!

Then an army of changelings from another hive attacks Canterlot.

Now all of ponykind knows that changelings are real, and his readers are sure to realize that the changeling in his book was too similar to the real thing to have just been based on a myth...

earlier chapters have been revised as of 7/19/13 to be more inline quality wise with the later chapters.

Featured on EQD 10/5/13!

Let it be known that there will be extensive changeling world building in the chapters to come.
