Faith of the Fallen

The series often mixes intense battles with deep philosophical themes. I'm curious if this was a deliberate choice to reflect the protagonist's inner struggle or evolved naturally through the story.

The book presents faith as empowering but also as something that can be exploited. How did readers interpret the author's message about religion and belief?

The political system, culture, and history are so rich. I'm wondering if these elements were mapped out extensively beforehand or developed as the story progressed.
