Theory on the series' ending, current hints are a red herring? (Spoilers)
The ending of Faith of Beasts lays the groundwork for a bioweapon against the Carryx, but not in the traditional sense: It could involve the Swarm taking over a Carryx to rebuilt itself into a Sovran. Or a 'fake' Sovran whilst the real one is incapacitated, which would send out the right subjugation signals and pheromones. In either case, the lack of agency of the Carryx would be exploited.
It would be funny to see the Carryx becoming slaves to their own nature, perhaps even being completely 'remote controlled' whilst being fully aware of the nature of the deception.
Having justice served like that would be a crowd pleaser for sure, but I doubt it will be that simple:
Red herring theory, actual ending: Knowing the writers, I'd assume the signs pointing towards this conclusions are likely a red herring and the bioweapon plan will likely fail (or be a success, but reveal that things are far more complicated than simply conquering the Carryx).
My money is on a completely different ending that will subvert expectations instead. I'd assume it's Swarm related. It just seems like the narrative potential of the Carryx is limited, we'd get a very simple ending to a complex universe, almost fairytale like, which wouldn't be an adequate fit. But there's still great potential to explore the Swarm and elevate its importance to the story, perhaps making it a late-stage antagonist.
Speaking against this would be that all of this would have to fit into one last book, as the writers confirmed three novels. That major shift could make the ending feel rushed.
Do you agree with this, or have deeper thoughts on how it will end?
