I, like many writers, don't spend one hundred percent of my time writing grand epics or fabulous tales. Sometimes I have to write smaller things, for the purpose of preserving a story idea for later or just as a way to sharpen my thinky bits.
A few of these will never be built upon, and that's okay. These are not all meant to become great things. Many of these will simply be forgotten altogether, and, while that hurts a bit, it's not a tragedy. Better for them to be remembered in spirit by a few rather than forgotten by me.
Many of these won't fit your definition of prose, and some may stretch your definition of poetry.

Explaination of the title:
If you do some background research on the changeling myths, you'll find that they were used to justify infinanticide against mentally difficient children. One of the disorders linked to the myth was phenylketonuria, which I have, and will have for the entirety of my life.
Thankfully, I am leading a normal (enough) life, and am proud to call myself my school's resident changeling. The way I see it, after mistreating my ancestors, and then teasing me for following my required diet, humanity owes me the rights to identify with whatever the changeling legend becomes.

There is a hidden village deep within the untamed forest surrounding Neighagara Falls. Should one ever journey to this village, those who live there will welcome them for a simple price: love.

When the village accepts a new family from Cloudsdale, a not-quite-altruistic pair of changeling siblings offer a young filly friendship and a chance to find her place in the strange village she hopes to call home.

Being an alicorn is wonderful... except when it isn't. There are plenty of things that put a damper on limitless vistas of possibility afforded by such a long life: Court, mortal needs and expectations, the occasional decade of ennui.

And the dreams, of course. Agelessness comes with its own special kind of dreaming. Celestia finds that her own "Inner Court" is a bit too literal, and it--and she--are troubled at the prospect of a near-immortal Twilight Sparkle.

If only she could articulate exactly why that was.

Part of the Monophysite Quartet, which also includes Celestia Isn't Real, Have You Considered My Servant, Twilight?, and The Esoteric Rites of Darkness. All four stories have a common origin point in an old story idea I called "Monophysite" and touch on who or what Celestia really is in some way. They are otherwise unrelated.

Appearance, talent, or attitude? Which is more important? What truly makes a mare who she is?

Spitfire asks herself these questions as she watches Rainbow Dash change her image to join the Wonderbolts. But does she really want to let the young pegasus she's admired for her skill and integrity change who she is because of a silly rule?

There is a tradition sacred to every member who has ever put on the storied flight suit, one that makes the wings itch to fly and brings a tear to the eye of the most stony-hearted of all pegasi.

Lead the way, kid. The sky's yours. We're right behind you.

Welcome to the Wonderbolts.

Scootaloo wasn't quite sure what she expected when she found a letter from her "secret admirer" asking to meet her after school, but it wasn't an invitation to the school dance. Nor was it spending Hearts and Hooves Day with Silver Spoon.

Rainbow Dash can’t wait for her first date with Applejack; they always have an awesome time hanging out, and a relationship just means there are even more physical activities they can try together. So when the dumb zap apple harvest postpones their date, she decides it’s the zap apples that are going to have to change their plans. Equestria should know by now that wild, ancient magic is no match for Rainbow Dash, especially when she might get laid.

Everything is going according to plan, until she crashes. Or, rather, until she wakes up after crashing and fifteen years have gone by. Fifteen years during which she seems to have been a very busy pony.

Now Rainbow Dash has to adjust to a life she never thought she wanted, and figure out if she’ll ever get to live the life that brought her here.

This story is a sequel to Iron Wing and the Demolition Crew

Everyone knows the story of the Iron Wing. They all know how fiercely she fought at the battle of Rainbow Falls. Soldiers measure their worth by where they were when she routed Sombra at the gates of Canterlot. Even now, there's a pilgrimage some take that follows her entire campaign.

And anyone who knows anything about the Iron Wing knows about the Demolition Crew. The story of the Crystal Collapse is one fraught with thrills and chills for fillies of all ages, and the closing of the Ghastly Gorge continues to inspire and terrify all who hear of it.

But legends seldom begin as the titans they become. Heroes are not born, but made, through fire and pain and loss. There isn't a pony alive who doesn't know the story of the heroes, but the story of the soldiers who became those heroes is one known only to them.

This is not the story of Iron Wing and the Demolition Crew. This is the story of Rainbow Dash and the Pie sisters.

Wheatland farms: the greatest source of food in Equestria. The ponies of Fillydelphia rely on it for bread, bakery products, and hay.

When a freak wildfire takes out an entire season's worth of crops, things are dire. The ponies of Fillydelphia are facing starvation.

Applejack hatches a daring plan. Accelerate the weather around her orchard, rushing through Winter, Spring, Summer, and Autumn, and reap another harvest in time before Fillydelphia's stocks run out. There's just one problem: all she has is a week.

For this to work, she needs a pegasus. Specifically, she needs a pegasus as nuts as her...
