Vana'diel, the stage where FINAL FANTASY XI is set, is a virtual world created by Square Enix and the players together. Just like the real world, a wide variety of things can happenincluding problems players can't (or shouldn't have to) resolve through the game itself. This is where a special member of the Square Enix team comes in: the Game Master (GM). The GM's role is to facilitate players' enjoyment of the game.
