Many years after sending her beloved protege to Ponyville, unease sits heavily on Princess Celestia's heart as her relationship with Twilight Sparkle seems to have cooled despite all they've accomplished together. On the advice of her sister, Celestia sets out to investigate and resolve the lost connection with her most faithful student. What does it mean to be a Faithful Student...or a Princess of the Sun?

Earned a six-star rating on Equestria Daily and featured on its very own TVTropes page!.

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

This is a realistic view on how shipping would actually happen in the show. Almost every pony has been shipped with everypony else, but this is what would actually happen if two ponies ever attempted at a relationship.

...

No offense to any shippers, even though you shouldn't take any. If anypony would like to see any other shippings done on this fic, just leave a comment. Maybe I'll write it if I feel like it.

When she chooses to pursue it against Celestia's wishes, she finds herself entangled in a messy history that some want forgotten. An Alicorn's position comes with sacrifice. And when given power, one will always be in want of more...

A complicated explanation for the history and intricacies of the My Little Pony universe. If you're reading this, be ready for the long haul.

A rewrite, or rather, the heavily revised and actually worth reading version of The Struggle for Power, my earlier work. Think of that as an alpha build, and this as the "released-to-the-public" program.
