When their wings were broken, the First-Born Sons tore off their heavenly cloaks and trampled them, burning their feet. Bound to the earth, they walked among men and assumed their appearances and their appetites. They took human wives and bore them children.
These children, the first-born of the First-Born, grew to be giants. Their fathers, in mockery of the Father who had banished them, taught them the Unbroken Language. It pained them, this language that was not meant for their mouths, but they learned it still and used it to raise monuments, shatter mountains, and split oceans. They spoke to the men of the cities, and the men, fearful of the way these words twisted their guts and groins, made them kings.
The second baby born to a woman who had lain with a burned First-Born was always a girl child. They were taken as consorts by the giants, though not one of them ever born a child for their cousins and brothers.
The third baby born—in those rare instances when a mother was able to hide herself from the wrathful giants who sought the source of the barrenness of their wives' wombs—was a small boy, a slight child who never grew to be taller than the shortest man in the village. Thus they were able to hide themselves from the giants and the Broken-Jawed Ones.
The third children were blessed by their fathers' Father. While they had never received any teachings of the language of angels, they knew it in their hearts.
It was these third children, hidden among men, who invented writing.
