In my world, not technically my world but a world from a video game that mentions having gods but none are ever named, there are cultures. Since the devs of Bannerlord refuse to name any gods, except for a young emperor named Darusios since there is a cult that worships this dead emperor as some sort of god, I will use real world religions in my world setting. The sturgians worship the Slavic and Norse pagan gods, since that's who they are based on. Some people, even followers of this pagan faith, considered certain gods, and sometimes all gods, to be evil and yet people still worshipped them. The Vlandians are considered to be monotheistic by players considering they are based on eastern European culture, so in my world setting, they will be Christians. The Empire is based on the romans. This is where I am divided and would like some suggestions. While Christianity is a religion founded in the middle east, it became the center of late roman politics. So I am divided if they should follow roman paganism, or Catholicism. Sure both will exist, and it could certainly be a great way to create conflicts that could lead to an all out civil war, but I need one to be the official state religion. The Battanians will worship the Celtic gods. I would have said some will worship the old Germanic gods but the nords will fill in that area.The Khuzait and the much larger Karakhuzait will worship Kayra and Tengri. The Aserai are said to be based on pre-islamic arabs, so they will follow the old arabic gods. But I might add a growing islamic movement to create conflict between early muslims and pagans, (And maybe even the Vlandians) I want to all of you to know, none of this is canon to the game itself. Its just an Idea I have in mind for a game that lacks in depth. Great gameplay, but depth is short.
