"With the Allagan ruins in the Carteneau Flats all but destroyed in conflict between the three Grand Companies, Alphinaud's new organization (whatever they're called) has taken the initiative to broker new cooperation between the city-states. In order to allow adventurers of all walks and allegiances to polish their skills to defend Eorzea, war games will continue in Carteneau without Grand Company restriction."

Oh how one paragraph of exposition could let me play with my friends whenever we want, and without treading on the all important story.
