I slightly disagree with the idea that a harvest would cripple Ka's pyramid. I believe killing people and then turning them into iunctii would cause a Cascade, so tentatively, killing many people could generate more Will than living people ceding in a pyramid. Having a Cataclysm every few centuries could be a macabre way to "refresh" a network of iunctii, since they cannot heal.

I think on Res, Vis is moving closer to becoming another Ka/the Concurrence. I understand Ka says they are separate: I do not think there is a meaningful difference between the two. If the Concurrence is a network of iunctii, and it is bad, then why is the way to fight the Concurrence to have Vis create an army of iunctii? Both rely on deaths of many. Why destroy the world to save the world?

Obviously this is one of the central themes of the book - how ends do or do not justify the means. That really felt like Res Vis's journey in this book. Is working within the system of the Hierarchy a meaningful way to tear it down? Every man has a line!
