Lusitania = Roman province, modern Portugal.
I always thought Lusitania was a reference to the ship that was sunk in WWI and prompted the US to declare war. Which, I think, is not a bad reference for a region name.
and while I can appreciate the "blank page" argument, its also nice to have some sort of indication as to the style of the city, ie. Wurzberg German style. I think of it as "lined paper", if you will.
