We all have lives, no problem about build time. Upon further reflection and reading more of the fourth part (I still have not finished it yet), however, that second point may not be as important as I had initially thought, since (a) I had forgotten that the Sands are basically a dreamscape where things have no obligation of making complete logical sense all the time, and (b) there are more numerous Christian references that are equally as unexplained (if not more so) from the view of ancient Babylonia. That being so, you can ignore what I wrote if you so desire, since I was about to delete it anyway until I noticed that you responded. At the end of the day, for this story, any real-world history is just minor window-dressing that does not need to be as fussed over as history-lovers like me may sometimes feel. I would be curious to see anything that you come up with, though.
