Story and setting. Now that you’ve figured out who your protagonist is and how they fit in to your premise, consider what happens to make your character start to move to achieve that goal and get involved with the overarching plot. This is what’s called your key event, also known as the Call to Adventure, and it usually happens by the end of the first tenth of your novel.
Action Plan: Brainstorm some circumstances that would disrupt the status quo, cause the protagonist to begin acting on their goal, or dramatically change their goal at the beginning of the story to the main goal that makes up the bulk of the plot or story. What is happening “on screen” action-wise? In the character’s mind/emotions? How is the theme reflected in the action and the character’s thoughts/feelings? Often a new person or thing that may have been foreshadowed earlier on is now introduced to the hero. But is your protagonist reluctant or eager to leave the world they’ve always known?
