Make plans

Think about how NPCs or monsters are likely to react to the PCs, or what might happen when the PCs enter an area, or how long after X will Y happen. Reflect this in your notes as…

… a descriptive sentence or two;
… one or more GM moves you can make;
… a series of if/then statements;
… a list of possibilities;
… a Die of Fate table;
… a custom player move;
… an impending doom and a series of grim portents;
… a timeline or timetable of events; or…
… a combination of the above.
