If you want to tell the best story possible, you can only do so with characters who are fully alive and made for the world that you’ve created— Not characters who are borrowed from a world that someone else created a long time ago. . . . Characters are storytelling devices that help the reader experience and process the story. If your character is one-note, your story will likewise fall flat. It won’t be as rich and nuanced as it could have been because your stereotypical characters aren’t able to carry the weight.
