THERE WIL BE SOME SPOILERS IN THIS POST SO BEWARE
From bob_5000
what I also would like someone to discuss (carlos?) is the meaning of the Idaho ghola. I don't wanna spoil anything, but I have been fascinated in how the story shifts away from leto and the fremen to the bene gesserit and their gola, and I would reall like to hear someone else's opinion of that.
Idaho or his ghola is the only character that is present in all 7 books written by Frank Herbert. As the time passes from book 1 – 7 Idaho becomes more and more of a pivotal character in the direction that the Universe takes.
The Duncan Idaho Ghola of Heretics of Dune and Chapterhouse of Dune becomes the super human as he has all the training from the Bene Gesserit and Bene Tleilaxu and also the Honoured Mates, plus whatever genetic engineering that the Bene Tleilaxu have given him. His only weakness that I can see is that he does not carry the Siona marker gene which hides people from prescience. This is why he remains in the stolen no-ship. Ultimately fleeing in at the end of Chapter house with a reborn Miles Teg (what will he become)?
The last 2 books in the series that are being written by Anderson and Herbert will examine, I believe, what happens to Duncan and whether he can become the next Kwisatz Haderach, or a person of similar power. Who will end up pulling his strings, the Bene Gesserit, the Bene Tleilaxu or the Honored Mates. Or will he go rogue and call the shots himself (more likely).
I think the books will have to explain why Duncan is so special. From memory Heretics of Dune and Chapterhouse of Dune do this to a certain degree, but it has been quite a while since I read these books. Possibly time for a quick re-read.
There is a definite similar thread that persists throughout the Dune series, the search or creation for the all powerful being, Paul, Leto, and now Duncan. Very similar to our world for those with a religious inclination, God, Allah, Jesus, Mohamed, etc.
The golden Path in God Emperor of Dune has opened up a vast universe by causing the scattering and ensuring the survival of the human race. This has also hopefully ensured the survival of the Dune universe in the written format, even if Herbert and Anderson stop writing after the ‘final’ two books I hope others will take up the pen and continue exploring, possibly franchised out which seems to be becoming quite common at the moment.
As a point of interest Dune was written 40 years ago! WOW
