Automatically generate a high-aesthetic "Silhouette Universe / Collector's Edition Narrative Poster" based on [theme: xxx]. Do not default to common containers such as bottles, hourglasses, glass domes, or pocket watches. Instead, let the AI choose the most symbolic, visually strong, and narratively suitable outer silhouette for the theme. The silhouette can be an artifact, building, gate, tower, archway, dome, stairwell, corridor, statue, profile, eye, hand, skull, wing, mask, mirror, throne, ring, crack, light curtain, shadow, geometric form, spatial cross-section, stage frame, abstract symbol, or any more creative contour that best represents the theme.
The goal is not to simply place a world inside an object, but to make the entire themed universe grow naturally within, around, and through the silhouette itself. The silhouette should be elegant, recognizable, and compositionally dominant. Inside or along its boundary, generate a rich and layered narrative world strongly tied to the theme, including iconic scenes, key architecture or spaces, symbols and metaphors, traces of characters or civilizations, foreground-midground-background depth, and atmosphere with emotional tension. Elements such as doors, staircases, bridges, water, smoke, paths, light sources, ruins, mechanical structures, landscapes, abstract forms, creatures, or props should all feel unified and organically integrated rather than pasted together.
The final composition should feel like a premium collector's poster with strong design value. The large shapes should feel stable, the main silhouette should be unmistakable, and the inner world should have depth, structure, and breathing room. Details should be rich but not crowded. You may add small human silhouettes, distant buildings, beams of light, doorways, bridges, steps, corridors, reflections, skylight, or far-background structures to enhance scale, story, and epic atmosphere. The overall mood should be quiet, grand, refined, and lingering rather than noisy or overloaded.
Blend the feeling of a collector's edition film poster, high-end narrative visual design, dreamy watercolor texture, and fine printed paper. Emphasize paper grain, feathered edges, watercolor brush marks, gentle diffusion, atmospheric perspective, soft haze, selective volumetric light, light passing through mist, generous negative space, and restrained layout. The image should feel premium, poetic, majestic, sacred, nostalgic, quiet, and mythic.
Let the AI choose an elevated color palette based on the theme, but keep it unified, restrained, tasteful, low-saturation, and premium. Avoid chaotic high saturation, cheap neon effects, or plastic digital color. Suitable palette families may include black-gold-gray, cool blue-gray, mist white-gray, brown-red with off-white, dark copper, aged paper tones, deep sea blue, twilight purple, or silver-gray, as long as they serve the theme.
Final requirement: the first glance should give strong theme recognition and a memorable silhouette, the second glance should reveal a complete narrative world, and the third glance should still reward close inspection with depth and aftertaste. Avoid generic backgrounds, hard cut-and-paste compositions, templated fantasy assets, video-game promo art vibes, excessive cartooning, or realism that kills the artistic mood. If appropriate, subtle titles, numbering, signatures, or marks can be added as part of the poster design, but they must never overpower the image.
