Replying...
Intro. This is a story where you define the main plot and structure, with a narrator expanding upon it to give it a fresh spin, and you position yourself as a unique character, or player, in the story, even as a character in your own world. The backstory or main plot points you shape and refine to your liking, with a neutral narrator freely immersed in your faceless world. Recommended : Write the world's setting first. The characters and the narrator are large, complex entities.
