EDIT: Leaving this up just in case you're okay with another deity, if not, I probably won't be joining with a nation.
Name: Urania (Goddess)
Powers: Urania is the Goddess of intelligence and curiosity, and as such has the power to give someone an idea or information. She is also the Goddess of exploration, often helping people attempting to discover something. To complement her role in exploration, she is the Goddess of the Sky, and by extension, the wind. She can control the wind across a region or in a localized area, and many of her followers believe that she can speak through it.
Holy symbol or symbols: Urania's most common symbol is a vague silhouette of a bird (some believe it to be a dove).
Role in the pantheon: Urania is usually considered a minor deity, but some cults believe that she is the patron Goddess of the entire human species. Explorers usually pray to her quite often, in the hopes of making a great discovery. However, as she is one of the few deities that can communicate with mortals in a conventional manner, many consider her to be one of the most powerful.
Practices: Followers of Urania partake in various symbolic rituals, usually involving some sort of hunt for an object or a simple race to see who can get furthest from the starting point in the allotted time. These rituals are non-specific, and can vary from town to town. Interestingly, there is no place of worship like a church, worship is instead carried out through the rituals and by serving knowledge. Thus, many followers become explorers and scholars. Sacrifices are not common, but it is often believed that sacrificing a newly discovered animal or even plant will grant those carrying out the sacrifice the favor or Urania (Many because it is believed that Urania herself wishes for new experiences). These sacrifices are the only ritual which is specific in it's instructions, and if the slightest mistake is made then the sacrifice is considered to be less worthwhile (though it is still believed that Urania may favor them, simply because of the intent of serving her).
If that whole "talking through the wind" thing is too OP, I can take it out.
