i like a lot of the theories so here goes mine same as some of the others but a little bit different. i think it was the blades after dealing with true dream they were thought to be aggressive, they went looking for vordin and didn't take we dont know where he is as an answer so they showed the military who reigns Supreme.
I was really curious how Paul is going to explain returning without a scratch after losing 200+ men, but the death of Truedream and his city as well as losing at least 1 military base, probably more would make a good distraction to not dig into the missing 200 much. Well done to the author for handling that issue.
