So, I read a post somewhere in this forum that showed a map of Cocoon. As it was, the only cities/towns that were mentioned on the map and in the game were Eden, Palumpolum, and Bodham. There's of course Nautilus Park and the other wilderness locations, but those aren't population centers. But, it's said that Cocoon is the home to millions of people - do they all live in these three cities? Or are there other smaller towns in between that just simply aren't mentioned? Eden definitely could be the home to over a million people, like New York or Tokyo, and Palumpolum seems fairly large as well. Bodhum, not so much. What do you guys think?

EDIT: note that I'm in the process of reading, but haven't finished, the prequel short stories to the game. so if the answers are in there...apologies
