@Ausar Can you do a bit more explaining on the religion side of things? They don’t seem to have a god or a subject of worship of any kind, and if that’s the case, they cannot be a religion. Unless, of course, you are saying that they worship the technology they use, which- this is just my opinion, mind you- is absolutely stupid. Please tell me that I’m wrong, and they do not worship the technology that they make with their own hands and that they do have a god for their religion.
To me, with this current setup you have, it seems that it would be better to make the wizards the people who DO have a religion; you could even say that their deity is the source of their elemental powers. That way, you could have the techies be the side that relies strictly on their own abilities and chooses not to believe in a religion. That, of course, leads to the problem of “if-the-wizards-obviously-get-their-powers-from-a-god-why-are-the-techies-too-stupid-to-realize-that-god-is-real?”
You could, of course, say that each side has a different god that they worship, one who encourages innovation and technology as part of their religion, and one who wants the people to stick with the old ways and develop their magic to better society and preserve the natural world. That way, neither side has a god on their side with the others too stupid to realize it is there.
Another option I could think of would be to say that the wizards do not like the teachings of the god who encourages technology because they think that the wizards should be the natural rulers of the land since they are able to harness magical energies and they do not like that a normal person can become powerful simply by utilizing a few machines.
Or, the god could have no connection at all to technology, and you could say that the god in some way pissed off the wizards in the past, and they have all vowed to never follow that god again and bring down the order that serves him. Or, scrap that very last part, and say that the church continues to hate the wizards because that’s what their god tells them, but the wizards don’t have any particular hatred outside of never again worshiping that god.
The only option that I would completely encourage you NOT to take would be to have no actual god. I think for this plot to work, there HAS to be some kind of a god.
Sorry for the long rant! I just wanted to get my opinion in here since you asked for different opinions!
