Personally I find it hilarious that the races are divvied up with a continent per alignment. One if the more expansionist races would have set out on a path of conquest by now.
Npc dialog when the first expansion lands(?):
"Gee Bob, did you see the sky last night, it opened up and spat a new city out of another world."
"Its ok Larry, they landed on Kingsreach so they're ok people to hang with, probably another Ranger race. "
