Twilight loves Celestia, though she had never had the courage to tell her until today. But it seems that forces have aligned to prevent her from being with the one she loves. Twilight fights against all odds to deliver the letter she had struggled so long to write. However, it may turn out that neither she, nor Celestia could possibly be ready for the consequences of their relationship.
Because being immortal does not mean being invincible. And a Princess is no more immune to pain than a pauper.
... especially in matters of the heart.

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.

Princess. Alicorn. The pillar of all ponykind, against which so many ponies often judged themselves. Celestia hates having to constantly be these things, and it's past time for a break. Luna will watch over Equestria while her sister is gone, but taking a break from your duties and taking a break from how the world sees you are two very different matters. Enter Prominence, a quiet pony who nopony really pays much mind to. Perhaps because she doesn't exist.

Aided by this disguise, Celestia will find her peace and relaxation in the home of one of the few ponies who know Prominence's true identity: Princess Twilight Sparkle. But when Twilight begins to see Celestia as a pony, and not a princess, can she deal with the feelings that arise? And are the feelings for Celestia, or for a pony she knows is not actually real?

One hundred years. Twilight Sparkle is having a tough time stomaching that reality. She has lived a full hundred years in Equestria, and being an immortal princess promises only more centuries to follow. She's not sure if she's ready for the rest of her life.

But Twilight's lifelong friend and mentor has a special gift for her, something that will change her perspective about the future.

Behind her calm and happy mask Celestia is a lonely alicorn. Once betrayed by a past love she has resigned herself to be alone forever.

But when a new love in the form of an old student is presented can Celestia let go of her sad past and take hold of a happier future?

And will the events happening around her be enough to make her realize that happiness has always been within her grasp.

Twilight Sparkle has been assigned to supervise the preparations for the Summer Sun Celebration. Simple enough, aside from the fact that eternal night may be looming over Equestria...and oh, yeah. She's in love with Princess Celestia.

A sweet bit of fluff for Valentine's Day.

Sticks and Stones may Break my Bones, but words may marry me? A careless promise by Celestia when she was teaching Twilight when the young princess was still a filly comes back to haunt her. Twilight has proposed marriage to her, and she can't outright refuse because of an ancient law that says royalty has the right to marry whomever they chose without question. Since Celestia is not above the law herself she has to come up with a solution, and she thinks she's found just that. Twilight has never been able to resist the Scientific process, so why not appeal to her sense of science? But having Twilight date other ponies in a social scientific experiment has not exempt Celestia, as there still needs to be a control group, which winds up being Celestia herself. Has she found the perfect way to get Twilight to see that there's somepony better suited for her than the Sun Princess? Or is Celestia really her one true love?

The Sparkles are a very old Canterlot family. Like any old family they have traditions. One of these traditions is that a Sparkle must do noble deeds to win their love-a tradition going as far back as Sir Prancealot. These are the noble deeds Lady Twilight Sparkle did to win the hoof and heart of Princess Celestia.

Now has a sequel! (https://www.fimfiction.net/story/362471/seasons-of-the-heart)
