Yeah, why do we go into the wall, but they're basically all walking freely in them? Oh, and if you're by the speaker, go off to that small balcony to the right of his entrance. If you look down to the right, there's a gaping hole in the wall protecting the city with a forested area in that hole. I thought that was really bad, because any enemy could basically breech into the city through that forest. So, there may be multiple walls. Kind of like the show Attack on Titan.
