No editing happened on this at all... I wrote it all in less than 5 minutes while I drank coffee. I really do think writing flash fiction improves the overall quality of my first drafts...
I could write this story into a novel... well, rather, I think it could be one of the 'drawer inhabitants' stories from this.
Once there was a castle by the sea which beat the shore with furious waves. They built a platform out into the water, hauling stone from a far off quarry, and there they called girls to sing the sea calm. Day and night they stood until their voices gave out, then the waves dashed their bones to sand.
Once there was a rocky shore, rich with tidal pools, rich with life, until stones were throw in and walled up. Sorcerers were called to sing spells, a war cry to frighten the corals, the barnacles, every small creature that could not swim away, those who had been crushed by the first assault. And though the invaders were fierce, the wind and waves did not tire, and they beat back each sorcerer to protect their smallest, most defenceless wards.
Once there was a great core of stone that was dug up, piece by piece and shaped into magnificent statues and architecture. But instead of becoming grand and admirable, some was shaped in rough blocks and cast into the vile, salty water. Instead of gleaming white in the sun and admired, it grew green and pitted, and the waves raged and tore, wearing each mighty block into sad, shrunken shadows.
And once there was a girl who was called to sing by the sea.
