Delivering Evil for Experts

Their motives and personalities felt layered rather than one-dimensional. I'm curious whether this depth was planned from the start or developed during writing.

While I appreciated the world-building, those sections made the story feel a bit sluggish compared to the action. Was that intentional to build tension or just how the story evolved?

The rules around magic felt fresh and detailed, which added richness to the story. I wonder if the author based it on any real-world concepts or created it entirely from imagination.
