Yeah, I hope she won't die. She's too cute to die in the hands of some ant monster.
The suit might have come from some drug trafficker or a smuggler. It's not like the border control and official propaganda would be the whole truth in a country that big. Goods would be certain to be smuggled in and people certain to enter unofficially. The no technology stance would also make it next to impossible to really control contraband and illegal entry. Even if a citizen saw something suspicious, what would they do? They can't make a phone call with no phones, and with the lack of modern technology they need to toil from morning till evening to eke out a living, so they can't afford to make a timely trip to report to anybody. So, any smugglers would have a free reign as long as they didn't draw too much attention. Not to mention the drug gang is probably sanctioned by the government.
