Book one; Descending Eagle, covers from his birth, through his first few years as a child, his flight down to the birdman's school where he learns to fly; his encounters with other peoples: some positive, some negative; his actions and reactions in each case. It ends up with his first battle with pirate raiders and his being sent to the City of Emperors with messages for the Emperor; it stops as he leaves the Commander. Is continued in "Cuauhtemoc: Descent of the Sun Priests."
