Most of the major cities have their own Patron Diety. Ishgard has Halone the Fury, Sharlayan has Thaliak the Scholar, Limsa Lominsa has Llymlaen the Navigator, Nym had Oschon the Wanderer, Ala Mhigo had Rhalg'r the Destroyer, Ul'dah has Nald'thal the Trader(s), and Gridania has Nophica the Matron.

Are the Twelve exclusive to Eorzea, or are there others who worship them, too? I would just be curious to know who the Domans, as well as the Xaela, revere, since it really says a lot about their specific cultures.
