Did they get that knowledge from 9 soldiers, one of which carries a cursed burden?

Even in this case, it wasn’t the random “good guy with a gun”. It was a member of the peacekeeping group setup by the event organizers. IE, it was their job.

Except for when it’s used for natural born citizens of course.

I’d be fine if they came back after realizing that the entire reason was to enrich the orange idiot even more.
