is their any deity or deities in this world?
The young King Julian is seen as a deity to some degree. He's an albino, pale skin, white eyes, white hair. He's also suffers from thrombocytopenia, which causes low platelets in the blood and thus means even a small injury could cause him to bleed out. Because of this he is hardly ever seen out in the open and when he is he is surrounded by The White Cross. His ailments are known by few and it is common belief that Julian is a fallen angel meant to lead mankind to a new age.
Though he is physically fragile he is highly intelligent. He's an adept strategist that has won several conflicts against the ever growing bandit threat. He is also highly interested in the forgotten age and has been successful to some degree in uncovering forgotten technologies. (The White Cross's double layered armor is a result of this) His intelligence has earned him respect and his ailments have created mystery, it is because of this he is borderline godlike.
Going back to your question, each region may have it's own gods though none are widely popular. The closest you would get to that is Arenious, the city in which The Illuminous are from and it's not so much a god people worship but the clergy itself. It is those people I mentioned before that have "magic". I don't want to spoil that too much now though because we're not roleplaying in that city just yet. Maybe when this is more popular I'll go in detail about each region/city.
Hope that helps.
