I'm a huge nerd for city builder games. The feeling I got was that I was preparing for some kind of invasion, but I really didn't have to prepare. The game gave me Black and White 2 Vibes with the story telling, like I was trying to prepare my people, but it seems like it was an auto resolved conflict at the end. I think it would be cool if at minimum you gave the player a cutscene of detailing the battle and how their actions impacted it. (Could be done entirely with 2d images, kinda how Age of Empires 2 tells it's campaign stories, which would lean heavily into the beautiful character art in this game)
