Hugo's chanting did not stop.
What he chanted was the secret of the Fire Transmitter and his brother "Ash."
"[Ash is named for what has burned and cannot be reignited; charcoal is what has burned yet can still be reignited. Yet both ash and charcoal were born before fire appeared, even before anything combustible existed.]
"[Charcoal will eventually reignite, drifting to the sky, parting from the earth. Thus charcoal rises from the original fire, while ash falls into the abyss—]
The great-grandmother is the mother of all dragons, and she was born before light and fire.
Just like the secret about Winter that the great-grandmother bestowed upon Annan: "[Winter] was originally a term used to describe the silence of the heaven at the dawn of the earth, like that of a dying elder; and the earth's hatred for all things that are about to pass but have not yet passed."
She is the eldest daughter of the earth.
