The Grand World Order was formed as a replacement for the original World Order. The GWO is similar to the original, except for the fact that it now encompasses Nova and it has many new universal rules.
The GWO keeps the balance of the world and is run by the four emperors of Astia, Nova, Niguard, and Sodai. It ensures that the world uses a universal language, Engla, a universal currency, Aurum, and universal terms. It also documents all of the flora and fauna of the world for knowledge's sake.
