It is unclear why the Guild might want Hayt to make Alia attracted to him, except that it will solidify Paul’s trust of Hayt. It also suggests that Alia, as an Atreides herself, might be an object of the Guild’s desire for an Atreides’ heir. Beyond the internal control over Paul that the Guild hopes to obtain with Hayt, they also hope to gain full possession of melange—the tool that is most directly giving Paul power in the universe. In this way, the Guild hopes to dethrone Paul both psychologically and materially.
