You know why I gave up on the Dune series?
It was the goddamned retcons.
Not the retcons of Kevin J. “Star Wars hack” Anderson and Brian Herbert. No. Retcons in the 2nd and 3rd books, written by Frank Herbert himself.
First, do you remember the description of the guild navigators we got at the end of the first Dune book? They looked like ordinary people, except with the very deep blue-within-blue eyes of heavy Melange use. And this was a surprise to everybody. Even though the Spacing Guild had been using navigators for around ten thousand years, no one had noticed that they depended on Melange to do their job. (Nor, for that matter, had anyone noticed in all those millennia, that the single most valuable substance in the universe was produced as part of the life cycle of giant worms that lived on the same planet. But that’s a rant for another thread.)
Well, we’re not one chapter into Dune Messiah (the second book), and suddenly Spacing Guild navigators are these hideously deformed, mutation-bred monstrosities that barely show a shred of their ancestors’ humanity, floating in tanks of Melange gas that everyone in the goddamn room can see. And everyone always knew that this was what Guild navigators were like. Not only did they look nothing at all like the navigators from the first book, their extreme Melange addiction was a known facet of society, and had been since the Guild first formed – thereby reducing the big reveal at the end of book 1 to a big headscratcher and “what the hell, Herbert?!” moment.
Second, do you remember how Other Memory was first portrayed in Dune? It was essentially a download of one Reverend Mother’s memories into the mind of another Reverend Mother. Jessica ended up with the memories of the Reverend Mother she’d done the trance with, as well as the memories that that Reverend Mother had downloaded from an earlier Reverend Mother, which she’d in turn downloaded from her predecessor, and so on, all the way back through the centuries.
Well, in Children of Dune (the 3rd book), Herbert forgets all about that. Now Other Memory is a purely genetic trait. Alia and Leto II (the second Leto II, anybody remember the first one who died in the first book? Of course not) have the memories of everyone in their genetic lineage, including people who were never Reverend Mothers. Hell, Alia even has the memories of Baron Vladimir von Evil, for crying out loud. No download took place. Those memories exist in their minds because Gene Magic™.
I couldn’t finish Children of Dune, even as an audio book to listen to on my long commute to work.
