Correct me if I'm wrong.
But is Ferelden say...Britain, Antiva is Russia, and Orlais France?
Well it's hard to determine what Ferelden is, the closest might be the USA in the time of it's birth. The whole slavery abolishment, occupied by a foreign force, discrimination against elves and such. As for Antiva, more like Italy in it's young, debauched ways and no Pope. Orlais is indeed France. Navarre I supposedly something like Spain, Anderfels something like the Holy Roman Empire in a weird sense, I haven't read anything on Seheron, Par Vollen is something like an Ottoman Empire and Rivain is the African part of the Ottoman Empire where people were converted to the Qun.
