Planche de Concept Art pour Anime Fantastique

Cinematic anime key visual and concept-art presentation board for a fantasy adventure titled "[Codex & GPT-Image-2]". The main hero illustration fills the upper portion: a vast ruined stone causeway high above the clouds at night, leading toward a circular observatory sanctuary with spires, antennas, and a glowing mechanism at the summit. A vivid aurora arcs across a star-filled sky over distant mountain silhouettes. Three travelers stand on the weathered, cracked bridge lined with glowing cyan runic inlays, stone balustrades, and pillars. In the center foreground, a pale white-haired girl in a flowing white robe and cape walks forward, holding a staff with a red ring ornament, wearing a calm and mysterious expression. To the left, a tall woman with very long dark purple hair and a dark cloak turns slightly away, looking toward the sanctuary. To the right, a red-haired young man in a brown coat stands with his back angled to the viewer, carrying a large dark weapon. Large title typography "[Codex & GPT-Image-2]" is placed in the upper right, with a smaller Japanese subtitle "[灰銀のアウロラ]" beneath it. A small Japanese tagline in the lower left reads "[旅は、記憶の先へ続いている。]". Beneath the main illustration, a horizontal strip features 8 monochrome and muted-color concept art panels: 1 heroine full-body costume turnaround, 2 heroine facial expressions, 3 heroine accessories and gear, 4 purple-haired woman outfit turnaround and details, 5 red-haired man turnaround and weapon, 6 architectural exterior elevation of the observatory, 7 architectural interior structure reference, 8 circular mechanical diagram. Along the bottom edge, exactly 4 environment landscape thumbnails: 1 ruined mountain road, 2 icy-blue aqueduct, 3 distant sanctuary hilltop approach, 4 grand cathedral interior hall. Aesthetic: painterly anime game pitch board, dramatic cool blue and cyan lighting with subtle warm orange title accents.
