I think the fact that your nation has cannons is completely op. Since we have till now not much other nations to compare it too I have to say the whole industrialization-aspect has to be changed. The technology level should be medieval. I realize that it is a big aspect of your nation but still. Sorry.

To your god, well... We already have a goddess that gives ideas and the final spark for a inventor, Urania. Also I don't like that you want to play your empire and its patron deity at the same time. The deal making aspect is very interesting however.
I realize that you put quite a lot of work into it.
