The Wall. What little we have seen of it, it has taken a beating. The atmosphere in the bizarre does not indicate what's clawing at the wall. It becomes clear, or is it, that the Wall is part of Fort Tarsus. Even clearer of what it's keeping out.. What do you think, was it built as a last defense? Is time running out for humanity behind the wall? Do you think we are the last defenders? Do you think it will play in the storyline?
