I have a question in regards to technology. I had an idea for a nation that is generally highly defiant, scientifically advanced, and has a disposition towards freedom and independence - worship of gods is extremely rare and generally discouraged, although not outlawed. It's not that they reject the existence, of gods, but they believe themselves capable of independent survival. My questions; 

1. Would they be unable to use magic?

2. How advanced could their tech be? I was thinking something along the WoW gnomes, if that makes sense

3. Could I even make a nation like that, or would some vengeful god have likely eradicated them?
