Hi all, I've been developing my new novel with that Snowflake method I referred to in an earlier post, which I find really helpful to organize my thoughts. I have three major characters and three entertwining story arcs, but I just realized - I have no antagonist! At least as far as a specific person, that is. The main antagonist is an object along with a set of circumstances that prevent the MC and the other two from reaching their respective goals. Is this ok, or should I work in at least one major antagonist that is an actual person? Thanks!
