But some twelve thousand years ago, the First Men appeared from the east, crossing the Broken Arm of Dorne before it was broken. They came with bronze swords and great leathern shields, riding horses. No horse had ever been seen on this side of the narrow sea. No doubt the children were as frightened by the horses as the First Men were by the faces in the trees. As the First Men carved out holdfasts and farms, they cut down the faces and gave them to the fire. Horror-struck, the children went to war. The old songs say that the greenseers used dark magics to make the seas rise and sweep away the land, shattering the Arm, but it was too late to close the door. The wars went on until the earth ran red with blood of men and children both, but more children than men, for men were bigger and stronger, and wood and stone and obsidian make a poor match for bronze. Finally the wise of both races prevailed, and the chiefs and heroes of the First Men met the greenseers and wood dancers amidst the weirwood groves of a small island in the great lake called Gods Eye."
