Foundation's Triumph

The mix of genres gave the book a unique flavor, and I'm curious what inspired that creative choice. Did the story evolve from one genre or was it always a fusion?

The intricate power struggles added depth, but I wondered if that slowed the narrative for some readers. Was this a deliberate choice to build tension?

The detailed worlds and societies felt so immersive — I wonder what the author's process was for creating such a rich backdrop. Was it mapped out thoroughly beforehand?
