I'm not sure if this is the right place; I apologize in advance if it isn't. I have a setting for a book I've begun writing. It takes place in modern day Europe (or North America - I haven't decided and I'm not sure how important it is). It centers around a young woman who discovers that she's a witch: to overly simplify, this means that she has the ability to manipulate nature and the "atoms of magic". Witches also establish a bond with a spirit from the "spirit realm". She befriends a few other witches and attracts the unwanted attention of a group of religious zealots who consider manipulating nature and consorting with spirits to be blasphemous. Here's what I can't decide on. Either the zealots are simply human beings who use modern weaponry and technology to hunt these witches, or they are people who are assisted by guardian angels from the "light realm", and they also have the ability to manipulate the atoms of magic. The choice does make a radical difference in what direction I may take the story. I cannot for the life of me decide where I want to go. The first option would inject the story with a bit of suspense and thriller, while the latter would lift its supernatural action elements to higher levels. Here's what I'm thinking: They're two significantly different directions and it really is up to me, BUT! Is one of these directions one that may have hidden traps unknown to me that could break the story? Is there something about one of them that has potential that the other does not?
