Is limited clairvoyance allowed?

I see! Yeah there's definitely a distinction between a character believing in a god VS that god actually existing outside of an idea. I'm new to the site and still trying to figure things out, so that really helps! 

I don't remember if there's a section in the guidebook specifically banning things like spirits/supernatural phenomenon, but it was probably obvious considering that things like opposable thumbs and unnatural pelts are already off-limits lol
