+## 1. DR. MIRA CHEN — Xenobiologist
+
+```
+Portrait of a young East Asian woman scientist in her early thirties, short dark hair, wearing a practical survey jumpsuit with medical kit visible at her belt, holding a portable bio-scanner in one hand. Expression: precise analytical focus, slight frown of concentration. She is looking at something we cannot see, slightly off-centre. Ink and pencil portrait, fine cross-hatching in the shadows, clean white background, 1984 science fiction paperback illustration style, head and shoulders composition --ar 3:4 --style raw
+```

+
+## 2. LIEUTENANT YASHTI KORR — Military Liaison
+
+```
+Portrait of a woman in her early forties, mixed heritage, close-cropped hair, wearing ARM-style body armour with survey secondment markings. Alert, watchful eyes — she is always looking slightly past you. Posture: controlled, military but not stiff. One hand is visible near a weapon holster. Expression: calm assessment. Ink sketch illustration, pen-and-ink with pencil shading, strong shadow beneath jaw and armour plates, 1984 science fiction paperback illustration style, head and shoulders portrait --ar 3:4 --style raw
+```
+
+---
+
+## 3. RR'RAAN — Kzin Combat Specialist
+
+```
+Portrait of a massive alien warrior: Kzin species, bipedal feline, nearly three metres tall, orange-red fur with faint dark markings on the face, round yellow eyes with round pupils, large translucent pink ears half-spread, broad flat nose, mouth slightly open showing needle-sharp teeth. Wearing salvaged Kzin armour with clan markings scratched into the breastplate. Expression: barely-contained predatory patience — the stillness before action. Heavy dramatic ink lines, deep cross-hatched shadows on fur, alien anatomy drawn with anatomical precision, 1984 science fiction paperback illustration style --ar 3:4 --style raw
+```
+
+---
+
+## 4. WHISPER-OF-DISTANT-WORLDS — Pierson's Puppeteer
+
+```
+Portrait of a Pierson's Puppeteer alien: two horse-like heads on long flexible necks rising from a rounded, deep-chested body, three legs ending in tri-hooves, flowing golden mane running between and over both heads. Eyes on each head are large, forward-facing, utterly unreadable. One head is looking toward the viewer, the other is looking elsewhere — both simultaneously deliberate. Alien physiology drawn with careful anatomical attention. Expression: impossible to read human emotion but the posture suggests calculation. Pen-and-ink alien portrait, gestural organic lines for the body and mane, precise linework for the facial features, 1984 Larry Niven science fiction illustration style --ar 3:4 --style raw
+```
+

+
+## 5. TOMAS VELD — Chief Engineer
+
+```
+Portrait of a stocky, heavy-gravity-world human male in his mid-forties, dense build and calloused hands, wearing an engineer's work coveralls with tools visible in chest pockets. Dark hair going grey at the temples. Expression: focused, patient, the look of someone who has diagnosed the problem and knows exactly how to fix it. A slight wry quality to the eyes. Ink sketch portrait, loose expressive linework for the clothing, tighter detail on the hands and face, 1984 science fiction paperback illustration style, head and shoulders composition --ar 3:4 --style raw
+```
+
+---
+
+## 6. SOLA REYES — Survey Specialist / Navigator
+
+```
+Portrait of a tall, willowy woman in her late thirties with distinctive We Made It features — slightly mobile ears just visible, lean build, a quality of alertness that reads as permanent. Wearing layered survey gear with a portable mapping unit clipped to her shoulder. Her gaze is directed upward and to the right, as if watching something enormous move overhead — the Ringworld arc, implied rather than shown. Expression: quiet wonder she refuses to acknowledge. Ink and pencil portrait, fine hatching in the hair and jacket, open clear linework on the face, 1984 science fiction paperback illustration style --ar 3:4 --style raw

+## Usage Notes
+
+- All images should be **black and white / monochrome** to match the 1984 paperback aesthetic
+- Add `--no colour, --no photorealistic, --no 3D render, --no digital art` to any that skew too polished
+- Target size: **42mm × 40mm print slot** (approximately 498×472px at 300dpi for print, or 630×600px at 150dpi for screen preview)
+- Each portrait should be **cropped to head and shoulders** for the character sheet slot
+- The finished art should feel like a **period illustration** — ink line art with pencil shading, not painted
