In the beginning, when the world was barren and devoid of life, I came to this world...
Pinkie may speak of how Equestria was made, but the world Equestria sits upon has more history to it than that. This is one perspective - or perhaps, the perspective.
This is so deep!
Brilliant. Just. Plain. Brilliant.
I like this a lot, except it doesn't really explain alicorns returning... or does it?
But yes! Fluttershy is perfection.
This is pretty neat. I like it.
You've come very close to showing us a sorrow only felt by a creator toward his creation. I particularly like the idea of being driven by will. There are a couple of songs that kept popping up in my mind as I read it. Intension and Right In Two, both by Tool. If you haven't heard them, I highly recommend giving them a listen! There's a video where they play right into each other here.
I always love a God-Cord fic, not nearly enough of these and unfortunately, few really touch upon the concept of the ponies finding out that Discord is God. Or, in a case like yours, when he drops the act.
PS. In Chinese mythology, there is something called a longma, a dragon-horse, AKA a draconequus. And the dragon you're thinking of are called Longs in Chinese, so you're right on the Money.
PSS I find it insanely amusing that Hasbro created a character that, in appearance and behavior, can be seen like a Asian Dragon or the MLP version of the Devil.

The creators of MLP wanted John de Lancie to do Discord like Q was done.
