Les Égarés et les Damnés (The Horus Heresy Seige of Terra t. 2)

The characters often walk a fine line between heroism and villainy, which adds depth to the story. I'm curious whether this was a conscious choice to reflect the grimdark universe.

While I understand the importance of world-building, the detailed negotiations felt a bit slow compared to the action scenes. Was this balance intentional?

The universe is so richly detailed and bleak — I wonder what drew the author to this particular setting and how much of it was developed from personal interest.
