What's "lv"? Latvia? I ask because it is, of course, Livagia
in the world in which Livagia exists. I don't know what Latvia
is. Hmm. If "lt" is (I guess) Lithuania, then that only really
leaves "lv" for Latvia, so Livagia would have to be "li" or
"lg", unless Latvia were "la" or Lithuania were "li" or "ln".
Who was it that decided these 2-letter country codes? Is there
a list of them somewhere? Were they first established before
the break-up of the Soviet Union (which would mean that
Livagia would have been assigned "lv" before Latvia became
independent)?
