Hydaelyn is also known as the Mother Crystal, but it doesn't seem like many people actually know about that. The main deities revered in Eorzea are the Twelve. Some are patrons of certain city states (Halone is the patron of Ishgard, Nophica is the patron of Gridania, Llymlaen is the patron of Limsa Lominsa, Nald'Thal is the patron of Ul'dah, and Rhalgr is the patron of Ala Mhigo), while others are revered by races as a whole (Sun Seekers revere Ayzema the sun goddess, while Keepers revere Menphina the moon goddess).Â
Other gods and goddesses are patrons of a lifestyle (Thaliak is revered by scholars and mages, Oschon is revered by wanderers). The pantheon is also inter-related similar to the Greek pantheon (Rhalgr is the father of Halone, Halone is the companion of Oschon, Ayzema and Menphina are sisters, etc.)
Personally, I have one character who is very religious - my Ishgardian Elezen, Reilan. He is an adherent of Halone, once a member of the Orthodox Church of Halone, but has since strayed from that particular chapter and now reveres her in his own way, interpreting her texts and teachings his own way. It's an unusual thing for an Ishgardian to do so, but his personal storyline has driven him to such a belief.
Here's the official wiki on the Twelve:Â http://finalfantasy.wikia.com/wiki/The_Twelve
Edit: Not the offical wiki. I let my fingers get ahead of myself there.
