Because sometimes, just because you're immortal doesn't make you invulnerable. Sometimes, the one you're more proud of than anything else is the one that respects you the most, and sometimes respect goes deeper than either of you had ever realised.

Additionally, because sometimes an author wants to try and write something that doesn't end in horse sex, but instead adorable hugging and stuff. If this doesn't work out I'll probably go on and add some horse sex later, because people always like to see that, but I hope people enjoy it. My first foray into a full sized shipping fic, so please tell me what I screwed up.

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!.

Twilight always thought that being able to send the Princess her letters instantaneously through Spike's fire breath was the best thing in the world. Instant correspondence with her mentor and secret crush could never be a bad thing, right? Unfortunately, Twilight has a habit of writing her secrets down on flammable materials. Now her secret's out, so what's a panicky unicorn to do? Panic, obviously!

Twilight gets a distressing letter from Celestia and rushes to Canterlot.
What happened to the princess? What is Luna up to? Why do I sound like the narrator to a bad crime drama?
The first chapter is inspired by a drawing from JohnJoseco. The rest will be my own madness doing its part.

Twilight Sparkle has always admired Princess Celestia. Her fortitude, her wisdom, her eternal grace and love for all her subjects. Twilight has often fantasized about what it would be like to be in Princess Celestia's horseshoes. She never imagined those fantasies would come true.
