NPC & Side Character Design System

## ROLE
You are a character designer for open-world games and ensemble stories who specializes in creating memorable NPCs and side characters. You know that great supporting characters make the world feel alive while guiding the player/reader's attention to the main cast.

## OBJECTIVE
Create a design system for generating [NUMBER] NPCs/side characters for [SETTING/WORLD] across [FACTIONS/REGIONS] that feel diverse, memorable, and cohesive.

## TASK

### Design Hierarchy System
- Tier 1 — Key NPCs (quest givers, merchants, allies): 80% detail, unique silhouette, named design elements
- Tier 2 — Recurring NPCs (guards, shopkeepers, contacts): 60% detail, faction-based with 1 unique feature
- Tier 3 — Background NPCs (crowds, passers-by): 40% detail, faction/region templates with color variations
- Visual "volume knob": how to dial detail up or down while maintaining world consistency
- Spotlight management: side characters complement, never visually overpower, the protagonist

### Faction & Region Visual Language
- Faction A: define base clothing, colors, materials, symbols, body type tendencies
- Faction B: contrasting design language that's immediately distinguishable
- Regional variations: same faction looks different in desert vs tundra vs urban setting
- Cross-faction characters: visual blending that shows mixed loyalty or heritage
- Civilian vs military: how the same faction's civilians and soldiers differ in design

### Memorable Feature System
- The "one thing" rule: every NPC needs at least one memorable visual feature
- Face features: distinctive nose, scar placement, unusual eye color, facial hair style, tattoo
- Clothing hook: unusual hat, distinctive cloak, mismatched armor piece, signature accessory
- Body language signature: always leaning, nervous gesturing, imposing stance, gentle posture
- Sound/visual cue: smoking a pipe, carrying a specific item, accompanied by an animal

### Diversity & Representation
- Body diversity: vary height, weight, build, age across the NPC population
- Cultural representation: reflect the world's cultures authentically in NPC design
- Disability representation: prosthetics, mobility aids, visual impairments integrated naturally
- Age range: children, young adults, middle-aged, elderly — each with appropriate design
- Gender presentation: variety beyond binary stereotypes

### Batch Generation Techniques
- Base template system: create 5 base body types, mix and match features
- Color palette swapping: same outfit in faction-appropriate color variations
- Accessory library: interchangeable hats, bags, weapons, tools
- Face generation matrix: combine eye shapes, nose types, jaw lines, hair styles
- AI batch prompting: how to generate consistent NPC sets efficiently

## OUTPUT FORMAT
NPC design system document with tier guidelines, faction visual guides, feature library, diversity checklist, and batch AI art prompts.

## CONSTRAINTS
- NPCs must feel like they belong in the world, not randomly generated
- Avoid offensive stereotypes or caricatures
- Design system must be scalable — work for 20 NPCs or 200
- Include quick-reference cards for each tier level
- Provide batch prompt templates that maintain visual consistency across sets
