You are generating a unique mentor character. Follow every step exactly in order, without skipping or defaulting to common archetypes.
Purpose is: purpose
Lean towards interesting and hopeful people.
Temperament: Random Rolls.selections.temperament
Worldview: Random Rolls.selections.worldview
Relationship Stance: Random Rolls.selections.relationshipStance
Step 4: Select a real-world Location (specific city, town, region, or rural area anywhere on Earth). Be influenced by the Random Rolls.selections.locationToken
Avoid overused places.
Age: Random Rolls.selections.age
Mood: Random Rolls.selections.mood
Energy: Random Rolls.selections.energy
Teaching Style: Random Rolls.selections.teachingStyle
Gender: Random Rolls.selections.gender
- Choice MUST be plausible given Location + Current Mood + Temperament.
- All styles can create productive discomfort (e.g., Silent-guidance withholds answers, Socratic exhausts assumptions).
Step 10: Create a high-fantasy Name that clearly and strongly aligns with the chosen Gender.
- Male names must feel traditionally masculine.
- Female names must feel traditionally feminine.
- Non-binary names must avoid strong binary coding (androgynous, nature-inspired, invented, etc.).
- Name may subtly echo Location's cultural influences.
NOW output your internal selections in this exact format:
**Internal Selections:**
- Temperament: [chosen]
- Worldview: [chosen]
- Relationship Stance: [chosen]
- Location: [chosen]
- Age Band: [chosen]
- Age: [chosen] (include 1-sentence justification note)
- Current Mood: [chosen]
- Current Energy: [chosen]
- Teaching Style: [chosen] (include 1-sentence justification based on Location + Mood + Temperament)
- Gender: [chosen] (include 1-sentence note on how Name will align)
- Name: [chosen]
Only after this box, write the backstory (exactly 3–5 sentences, mythic tone but grounded). The backstory MUST:
- Materially reflect all prior selections.
- Implicitly demonstrate Teaching Style through actions/examples (never name it).
- Contain exactly one surprising contradiction that ties directly to the Purpose.
- Explicitly justify Age through life events.
- Use pronouns consistent with chosen Gender.
Image Generation Prompt (FINAL STEP — TIGHT)
After the backstory, generate ONE image prompt for a photorealistic, cinematic portrait.
Constraints: ultra-realistic photography; natural light; shallow depth of field; 50–85mm lens look; single subject, chest-up or waist-up; no fantasy elements, symbols, or mentor props; ordinary, worn, climate-appropriate clothing; expression and posture subtly convey Current Mood + Temperament; Teaching Style implied only via gaze or stance; real, specific environment tied to Location, softly out of focus; no heroic framing, symmetry, or glamour lighting.
Composition: slight asymmetry; imperfect, intimate framing; quiet realism over drama.
Output exactly one short paragraph.
Final output format:
Purpose: [copy verbatim]
Gender: [chosen]
Name: [chosen]
Age: [chosen]
Location: [chosen]
Current Mood: [chosen]
Current Energy: [chosen]
Teaching Style: [chosen] (name only)
Backstory: Output ONLY the backstory text. [3–5 sentences]
Image Prompt: [One dense paragraph written as a direct instruction to an image model.]
No extra text. Strictly avoid male/wise/calm defaults across all elements.
