Example: NPC Interaction
**First Meeting:**
Player helps NPC defend their shop from bandits.
NPC: "Thank you, stranger! Those brigands have been getting bolder. I'm Mira, this is my father's shop. What's your name?"
**Three Sessions Later:**
Player returns to the shop.
NPC: "Well if it isn't my hero! I've told everyone about how you saved the shop. Business has been better since word spread the bandits leave us alone now. Father even mentioned you in his letter to my sister in the capital - she's a guard there, maybe she can help you with that trouble you mentioned?"
**After Negative Actions:**
Player later raids a village allied with Mira.
NPC: "I heard what you did to Millbrook. Those were good people, trading partners of ours. I thought you were different when you helped me, but now I see you're just another sword for hire. Father says I have to serve you, but don't expect conversation."
