"...because of its nearness to populous Gray, our choth receives more humans into membership than most." (p. 1)
Pictures of Gray, then of winged Ythrians and human beings with gravbelts flying together. The words and the pictures begin to explain "choth."
"Rennhi...is remembered for writing The Sky Book Of Stormgate."
The accompanying visuals should hint at the contents of the Sky Book, which is a volume that we never read or, in cinematic terms, a film that we never see.
"In this, as you well know, she traced and described the whole history of our choth. Of the ancestors upon Ythri; of the founders here upon Avalon; of the descendants and their doings unto her own years..." (pp. 1-2)
Scenes on two planets, showing the differences between their environments.
"God stooped upon her before she could begin the next chronicle." (p. 2)
"'In the end, God the Hunter strikes every being and everything which beings have made. Upon your way of life I see His shadow.'" (p. 407)
"...that race with which ours is to share this world until God the Hunter descends upon both." (p. 434)
God the Hunter should have a distinctive musical theme accompanied by a darkening of the scenery.
"Then came the Terran War..." (p. 2)
We should see scenes that we recognize from the dramatization of The People Of The Wind.
"...and, when it had passed by, ruined landscapes lay underneath skies gone strange."
This should be easy enough to visualize.
"Hloch, who had served in space, afterward found himself upon Imperial planets, member of a merchant crew..."
We should recognize planets from other parts of the Technic History.
"...Hloch had wearied of the void and returned to the winds."
A visual of the void, then of winds.
"This is the tale, told afresh, of how Avalon came to settlement and thus our choth to being. This is the tale as told, not by Rennhi and those on whom she drew for the Sky Book, but by Terrans, who walk the earth."
Intersecting streets; many human beings walking purposefully; birds' eye/Ythrians' eye view.
