Location, location, location. Where is your story set? If well developed, place has the opportunity to become a character within a story. Part of my story takes place in a night club. Originally, the location existed in a certain place in the city. As the story developed over several re-writes, that location no longer seems valid.
For today’s prompt, think about locations in your story. Are they merely a backdrop, like the curtains in a room and of little significance? Or are they more important, setting mood and tone for your piece? Have you given enough weight to setting? Could you give it more importance, allowing it to become a character in its own right?
