ok, forgive me if anyone has posted this before but…
I just thought of something recently. The Red Line is REALLY high up, right? At least, for the most part, it is. So, you have to think, not many people from the rest of the world go up to the Red Line, but there has to be a city or 2 up there. I realize that Reverse Mountain is so high water freezes there, but that's not to say all of the Red Line is like that.
My point is is that, if there are people up there, not many of them have seen anyone from the seas, especially not pirates, since the only known way to get to the top of the Red Line is through Mariejois. I've just been thinking, if people live up there, it must be a whole different world..
