The goal of this list is to provide a quick prompt that is both detailed enough to easily spark the GMβs imagination and also vague enough to leave them enough room for improvisation. Part of this prompt is what I call the Face, or βWhat the other are noticing when encountering this NPCβ. It is not limited to visual, as it includes a peculiar look, a specific way of dressing, but also how they speak or move, and what do they βfeel likeβ overall. This appearance should be striking enough so that this character will be remembered with it alone.
