Eorzea plays host to numerous civilian organizations, both great and small, which represent the many and varied interests of her people. Three of the largest and most influential of these take a keen interest in adventurer activity. They are the Brotherhood of the Broken Blade―a group of vigilantes who are convinced the beast tribes will one day destroy the realm, unless they destroy them first; Azeyma's Shields―self-proclaimed protectors of the weak and enemies of evil; and the Horn and Hand―a band of scholars and scientists, merchants and moneylenders who seek to gain fame (and fortune) by aiding in the outfitting of adventurers. To extend their influence throughout Eorzea, each of these “factions” sponsors levequests which coincide with their particular area of interest.
As you can see, they don't offer much to the current story either mechanically or lore-wise that isn't outdated or done elsewhere. Would be fun to see them repurposed. But if going by the Tales from the Twilight, we may see the father of all outdated organizations get a nod first, lol.
