Good to see even when humanity is basically gone class segregation still exists. The parts of the city closest to the first wall of defense is the slums (poor people). Then there is a gap and the next part has small buildings, 2-4 stories high, so maybe condos for the not so poor. Then at the very end you see these two towers rising out of the ground (most likely a force field bubble/shield of some sort) to protect the part under the traveler which is highly illuminated and the farthest thing you can see is most likely skyscrapers, where if anything the most elite live at since they feel the worthiest to be living so close to the traveler, or could be religious buildings, since you know anything that we can't explain would fit under the category of deity or God. Well anyways still glad to see that the rich still get to -blam!- over the poor.
