[@Infichi] Not entirely sure. I know I don't wanna start in the East as that is considered the easiest or weakest sea(can't remember the actual term they used), but don't know much about the others other than I think the [hider=spoiler?]South Sea is where Sanji came from? IE Germa 66[/hider]

That's one reason I am asking.

that's north blue you're thinking of :D 
[/hider]

So you've go the four blues-

North, East, South and West!

North Blue from what we've seen tends to have more winter like Islands, there's some non-winter islands but most of them seem to see a lot of snow. That means there's a lot more room for making your own islands up, just post in the OOC "Hey, I want to have an arc, im thinking of this for an island" and as long as it's not too extreme for the area (like, North blue, but everything is future tech and flying cars!) it's all fine! (future tech and flying cars is basically... all go for the grand line though. That place is weird.)

East Blue is generally considered the weakest blue, because the strong pirates there are considered weak by normal standards. (Yes, Buggy, Arlong and Krieg were the strongest of the sea... and you've seen buggy.) In general, the base pirates of that place aren't very strong. But it is the home of Gold Roger!

South Blue: Not much is known here either, but it is home to some fine gun makers and Karate island! So generally, It's a sea that's good for tech, medicine and fightin!

West Blue: Home to scholars and cuthroats of impressive degree! Also home to some great musicians! Interesting place, not much else is known about it.

What's great about this, is how much freedom it offers, to generally be able to make up nearly any kind of story you'd like!
