Prompt template
My game is (genre and world, e.g., post-apocalyptic survival / a fantasy town), and I need to design an NPC: (role, e.g., grocery-store owner / mysterious information broker). Please: 1) write this character's persona card: backstory, personality traits, speech habits, catchphrase, and default attitude toward the player; 2) list what they "would never say" (secrecy settings); 3) write 6 sample dialogues: first meeting, everyday small talk, a trade, the player angering them, revealing a plot clue, and farewell; 4) give a system prompt I can feed directly to a dialogue AI engine so the character stays in persona during improvised conversation.
