Like, I don’t think passports exist, right? Could a person travel to another Empire/Kingdom?

    At some point wasn’t it actual stone walls around cities, with guards at the gates checking people?

      I mean… one of the great wonders of the world is literally a border wall with its own border patrol that was placed on it. Albeit a lot more complex than that, but that’s sort of the gist of it. It helped to keep “invaders” out and operated as an early warning system, but effectively was a border patrol.
