A Rising Tide
Since before recorded history the Western Wall stood along the shore of the Golden Sea. It was matched with its sister, the Eastern Wall some thousands of miles to the east. Both were tremendous artifacts of architecture.
The Western Wall was hundreds of miles long, a marching procession of fluted towers and delicate arching buttresses. However, some hundred years ago a great natural disaster swept the western coast destroying the lands. What began as minor earth tremors, built into a staggering earthquake which fractured the coastal cliffs. Mere hours later horrible giant waves battered the coast, dragging entire villages out to sea. In the aftermath the coast had retreated a hundred miles inland, leaving behind an archipelago of small islands and fragments of the civilization that once was.
The remains of the wall still stand on some isles. Delicate fluted towers, and fragments of buttresses, that stand impervious to every storm that has happened since.
