For this story helper, use the three words however you want. Plot points, ideas, objects in the setting, MacGuffins. Whatever your muse dictates.
Remember: Even if what you come up with doesn’t make sense, keep it and come back to it later. If your muse is like mine then it most likely enjoys giving you puzzle pieces that need to be fit together over time rather than the whole story all at once. You never know what will connect your pieces together, so don’t trash something just because it doesn’t seem to go anywhere right away.
