I thought it might be interesting to discuss the beliefs or the protagonist of your current work in progress and see what range we have.

My current WIP is a fantasy with an elven protagonist. He uses magic as a spiritual force that is generated by the land. Thus he is a person that deals with magical energy and see people as having innate abilities to store and use this energy, which comes in two forms. However none of the characters in this book refer to God or Gods at any point. This is simply how it is designed and I dare say the average reader would not notice it. There are a number of powerful but non-god entities in the story including dragons and a kind of vampire.

The main thing I found interesting is that it took some effort to remove colloquial use of 'god', 'soul' and similar terms from the dialogue even thought they really don;t fit the cosmology at all.
