Start with a belief
Write one sentence your character currently believes, such as “asking for help makes me weak.” Then choose a desire that puts pressure on that belief. The belief gives the character a recognizable pattern while leaving room for change.
Create opportunities, not milestones
List three situations that could challenge the belief: a friend offers help, a plan fails alone, or another person asks for support. Do not require these events to happen. Offer them as possibilities and let other players’ decisions shape the route.
Notice small changes
Character growth can appear in a different question, a delayed reaction, or a choice to stay when they once would have left. Record those moments after play. If the character doubles down instead, that can also be a meaningful development.
Share the arc
Tell collaborators the kind of scenes you are open to, especially if a topic is intense. Ask what they want for their characters too. An arc succeeds when it creates playable choices for everyone, not just a performance for one player.
A three-session experiment
For three sessions, note one moment when your character’s belief helped them and one when it cost them something. At the end, decide whether the belief is stronger, weaker, or simply more complicated. Let the answer emerge from play. You can change direction without treating the arc as a failed plan.
