The Doctor has lived a long life, and he's seen a few things.
He walked away from the Last Great Time War. He marked the passing of the timelords. He saw the birth of the universe, and he watched as time ran out, moment by moment, until nothing remained. No time, no space, just him. He has watched universes freeze and creations burn, he has seen things you wouldn't believe; he has lost things you will never understand. And he knows things: secrets that must never be told, knowledge that must never be spoken, knowledge that would make parasite gods blaze.
But in 909 years of time and space, he has NEVER seen ANYTHING quite like where he just found himself.

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?
