You are laying on the ground inside of an forest of your home town in the East blue, watching the midnight sky. Sooner or later, you'll sail these seas, and either climb up the ranks of the Marines, or become the greatest pirate in history. But there is other occupations - Bounty hunting, doctor, Mercenary etc's - You can take any type of path, some path would have heavily or light choices and consequences on the World. But now, you got to choose your path, and the way of your life.
