Epigraph for "Chapter" 87 (VII.4), p. 449:
OK...so does that mean that the entirety of PoD itself is an in-universe text, or that there just happens to be a book by the same title in the Duniverse and written by Irulan?Arrakis: Men saw great danger there, and great opportunity.
—the PRINCESS IRULAN, entry in Paul of Dune
I'm certain that they did this intentionally and that they're going to use this ambiguity to get out of any inconsistencies-related criticism of the book by blaming it on Irulan.
It's bad enough when they blame us for not liking their books. It's cowardly and despicable to blame their own mistakes and changes on a fictional character who can't defend herself.
Neither Kevin nor Brian has a ball between them. I wonder how much the testosterone shots run them a month....
