I think inspiration can come from anywhere; and personally most of my nation came from watching a David Attenborough show about the differences between the North and South poles. I haven't looked too deeply into dominions, and I'm sure Cyclone is right in what he's saying; but it's Klonsters choice at the end of the day. If someone wants to completely copy something else and it fits the setting then I see no qualm with it. Props to everyone else for original ideas tho
