I was shopping in Ul'dah today...
In the Ul'dah Mercantile House, Zawawa says: "Shop at the Seventy-seven Caravans of Ul'dah, and see your coin well spent!"
In the Limsa Mercantile House, Diving Eagle says "Come one, come all to the Seventy-seven Caravans of Limsa Lominsa!"
Are both of these factions supposed to be called the 'Seventy-seven Caravans'? And if so, why do both cities have exactly 77 Caravans? Is there some trade law i dunno about?
