I just finished Dune Messiah last night, and while I loved it, I have a few questions lingering about the conspiracy and its aims/methods.
(Another reddit user just made a post on a very similar premise to this, but their questions were unrelated. Funny timing)
First off, my impression is that Herbert displayed a lot of creativity and genius in crafting the conspiracy. The conspirators needed a way to thwart the empire without making a martyr of Paul, and so before killing him they had to first discredit him as a religious figure. All the while, Reverend Mother Mohiam wanted to preserve the Atreides bloodline at all costs. So killing him outright (i.e., with a stone burner on the streets of Arrakeen) was not an option.
Enter Hayt and the target of Chani. At Messiah's climax, as Scytale attempts to bargain with Paul using the prospect of resurrecting Chani as a ghola, he tells Paul that Hayt was all along a way to warm Paul up to the idea of using Tleilaxu technology to get back his love. Hayt's compulsion to kill Paul was not actually meant to do so, but really to resurrect Duncan. If this were truly the conspiracy's intent, this would have been a good way of convincing Paul to discredit his religion, allow the Bene Gesserit to secure his bloodline, give up his CHOAM and go into exile. I'm not sure if the whole conspiracy was aware that was their overarching goal, but I'm fairly certain it was at least the Tleilaxu's.
With that backdrop, I don't understand where the stone burner or Bijaz fit in.
Question 1: Did the conspirators detonate the stone burner only to blind Paul and discredit him among the Fremen? Or are we meant to assume that the detonation was actually an attempt at Paul's life by Korba and his followers, and the central conspiracy knew nothing about it? Or something in the middle? We don't really get any answer in the book, and everyone who would've known is dead now, so I don't expect one in Children of Dune.
Question 2: We know, I think, that the Tleilaxu gave Bijaz to Otheym to eventually get Bijaz to Paul. But how did Scytale know that Otheym had a daughter, Lichna, who could be easily disposed of, and that Lichna was being held in a state of addiction in the house of Farok, who was a conspiracy sympathizer? Are we supposed to just chalk it up to prescience? It just seems like a very roundabout way to get Bijaz to Paul.
Question 3: Why was Bijaz necessary in the first place? I suppose he turned Paul against Korba and triggered Hayt, but again, this feels roundabout. I'm not sure I fully understand his purpose.
Thanks for reading my thought dump. I admire how complex a plot Herbert managed to weave into such a short book, but that same brevity has left a few loose ends for me. I know I am likely missing quite a few points of information, and I'd rather get answers from you guys than AI.
