Didn't /Dzurlord/ say that Dragaera is basically Europe? That is, Elde Island corresponds to England, the uncrossable mountains might be the Alps? At a wild guess, I'd suppose that Northport is similar to Flanders and Adrilankha is near Bordeaux, with Dragaera City having been Paris, but my knowledge of 19th-century European politics and geography are not very developed. :) I remember thinking during /PotD/ that there was a lot of geographical information that it would be fun to go back and reconstruct, but it didn't immediately translate to anything I recognized at the time.
