12, Worship, Clerics

[Anonymoose]

Most of the 12 are worshiped most centrally in the areas where they are attributed the guardian deity. This is especially true of Nald'thal, guardian deity of Ul'dah, who has shrines both in the city and in Thanalan.

Yes, each of these gods is also related to an existing deity in some fashion, usually a member of the Greek panthon, as FFXIV is based on ancient Greece. I'll avoid that.

Here, I'll stick to answering just your question of where are worshipped. Those without central worship areas may appear later in new areas, or maintain the genreral world-wide audience, as the ones that are left out don't have very specific areas of specialty that are associated with the cities.

Halone - Ishgard; associated with War
Menphina - Keepers of the Moon Miqo'te; moon deity associated with love.
Thaliak - Sharlayan; Associated with Wisdom
Nymeia - No centralized worship; associated with the heavens and fate (Worldwide worship?)
Llymlean - Limsa Lominsa; watcher of the sea.
Oschon - No centralized worship; watcher of mountains/nomads (Worldwide worship?)
Byregot - No centralized worship; the builder (I bet we'll see more of him after the cataclysm)
Rhalgr - Ala Mhigo; associated with destruction; Highlander Hyurs as well.
Azeyma - Seekers of the Sun Miqo'te; Sun deity associated with inquiry
Nald'thal - Ul'dah; associated with transactions and death
Nophica - Gridania; associated with nature and the harvest
Althyk - No central worship; associated with time and change. (Worldwide worship?)
