Casa Capitular Dune

Frank Herbert's world-building always felt so layered—I'm curious how he planned the political and ecological threads for this installment. Was it mapped out from the start or developed as he wrote?

The conclusion left me pondering what really happened next—does the story imply a new direction or just a pause? Would love to hear others' thoughts on the open-endedness.

The desert planet feels so symbolic, but I wonder what motivated Herbert to pick this particular environment for the story's climax and themes.
