No. None of those. Rapture was a city in the middle of the Atlantic Ocean. We don't have any of those other places in my world. Likely it is only a oddity of multiple worlds having multiple uses of the same languages under different names. With the near infinite possibility of universes parallel to each other, it's not difficult to believe. Though it was not something I thought much on prior to my arrival here.

This is my first time in... or on, I suppose, a flying city. Are yours more what I assume are the traditional sort? On land and not under the water or among the clouds?
