The King's Road
The King's Road is a story written by Tsukizubon Saruko (月図凡然る子). It ran in Special Issue 5 and can be read on LJ, and is mirrored at http://www.shousetsubangbang.com/mirror/the-kings-road/.
"It had all happened so quickly.
Consciousness crept back in slowly, reluctant to be complete: like dawn breaking on a dark and cloudy day. Her head hurt, and fresh pain seemed to jostle into it with every rocking, jerking movement under her. She was, Cybele became dimly aware by degrees, slung face-first and sideways over the withers of a galloping horse, close against the knees of some rider who was holding her steady with a hand in the small of her back. Her arms were stiff, her wrists bound together behind her. She could see nothing, and perhaps it was the darkness in part that accounted for her confusion; some scarf or cloth had been bound around her eyes."
It kind of ended up being gender-swapped Balthier/Vaan, and I'm surprisingly okay with that.
