So here is a brief text to try and now set up the prologue narration…
Yes, text + narration might work. It’s uncommon but it might work here.
I’m looking at the Emperor - Battle for Dune cutscenes, and you have two fremen discussing Harkonen oppression there (second Atreides cutscene). Quality is too low to use the visuals, and there’s music in the background. But it might be usable.
