Rirten grew up in a small community of some 30 people, and in school had closely associated with only about 50 teachers, professionals, and fellow students. Even just the Stranger’s Bar was a crowded and exciting place compared to back home. Which was nice! Crowds, even alien ones, helped their pheromone bath feel less disconnected from reality, and excitement was always fun.
The problem was that this kind of background made it hard to truly appreciate the scale of things. The largest conflict Rirten had ever seen had been a dispute between two villages over fishing rights, and that had been over before it had even began- about a dozen from each side had squared off, and the side with the least physically-imposing members had surrendered. Northerners were not made for fighting and prefered to resolve conflicts by avoiding them in the first place.
The idea of a space empire with space battles was hard to understand in that context. The idea of a space empire with space battles deliberately wiping out other civilizations... well, that was just unfathomable. They just didn’t have the sense of scale for it, or the context needed for an appropriate reaction.
Rirten had to just think of it as an especially large and violent village conflict for now, and get the appropriate sense of scale later. Olsh probably had footage of the fight with the last space empire- they would have to talk her into showing it to them. “We don’t have any tech to loot, and we don’t use the same resources you do. Why would you attack us?”
