There's absolutely nothing wrong with having a Raen character who's a priestess or self-styled priestess of the Dawn Father, Azim. That said, there is no such formal religion or resulting priesthood surrounding the Dawn Father in the lore yet.
Why? Because most Raen don't actually worship the Dawn Father. The Raen, who have long since abandoned their ancestral lands, most often adopt the culture and customs of the land they settle and live. In the case of most Raen, this means Yanxia, the Ruby Sea, and Hingashi. In these lands, the kami are worshiped and so the majority of the Raen likewise revere or worship these same kami.
Where we see the most worship of Azim is in the Oronir tribe, who, while Xaela, believe themselves to be descended from Father Azim. However, this differs from many of the other tribe's views of the Dawn Father and Dusk Mother. This complicates a single organized religion of either deity, as beliefs surrounding the worship of the two Auri deities varies between tribes. For instance:
Hope this helps somewhat! Like Liadan pointed out, the scope of our information regarding clergies, religious groups, etc is very limited (with most references to Halone, Nald'thal, Rhalgr, or Llymlaen. You get the occasional mention of a pilgrim, devotee, or maiden servant of another deity (Menphina comes to mind) but beyond that details are scarce. For Stormblood, it's the kami that get most of the focus.

Baatu Wrote:Some say that the dominion of the Dawn Father and the Dusk Mother does not extend beneath the water. But ours does. Indeed, the Oronir fear naught above nor below.
Hien Wrote:Temulun Khatun taught me but a fraction, you see... How this world born of the gods was to be their battlefield, their creations to fight in their stead. How Azim, Father of the Dawn, he who birthed the sun, and Nhaama, Mother of the Dusk, she who birthed the moon, made the Au Ra... Yet though these children warred for a time, eventually they laid down their arms and came to love one another. And so the gods bequeathed this world to their children, and ascended to the heavens whence they came. Those born of the Dawn Father were called the Raen, and those born of the Dusk Mother were called the Xaela. So it was and ever after.
Udutai Wrote:Before we begin, tell me: what do you know of the Au Ra, and how they came to be? Yes, yes. A common tale, and one believed by many tribes. But what it does not mention is this: Azim and Nhaama were lovers. Oh, they fought in the beginning, as did their creations. That much is true. But when they saw how the Xaela and the Raen rose above their hatreds and joined hands in harmony, their hearts stirred, and the love their children shared became theirs as well.
Alas, he was of the sun and she of the moon. Apart they must remain, lest day and night cease to be, and with them all creation. With sadness in their hearts they returned to the heavens─he to the day, she to the night, destined to walk before and after, never to meet. As time passed, Azim's yearning for his beloved grew deeper still. Was there truly naught that could be done, he wondered. At last, he knew.
"If the Father cannot be with the Mother, then he shall go amongst her children. Now and ever after.“ So it was that Azim took a fragment of his being and with it fashioned an avatar. Clad in scale of midnight, he descended, and sought out the Xaela. Yea, he was the first Oronir. We are of his flesh and his blood. We are the children of Azim, and it is our duty to watch over and keep the Xaela safe.
Dotharli Youth Wrote:It was only a few weeks ago that both my mother and father were taken from me by the heartless Oronir. Their deaths made me realize that I must commune with the Dusk Mother. I shall pray that she strike down those who pretend they are the children of Azim, and that she continue to nurture the Dotharl. Nhaama resides in the House of the Crooked Coin to the north. I have heard many tales recently of pilgrims being slain by the monsters that lie in wait along the trail.
