Based on [TOPIC: xxx], automatically generate a high-taste "Silhouette Universe / Collector's Edition Narrative Poster" artwork. Do not confine the scene to fixed objects or common containers; do not default to bottles, hourglasses, glass domes, pocket watches, or other routine vessels. Instead, let the AI, guided by the topic, decide and pick the single most fitting, most symbolically loaded, strongest-silhouetted, most suitable primary-silhouette vessel for carrying the full narrative world. This primary silhouette can be an object, architecture, a door, tower, arch, dome, stairwell, long corridor, statue, side profile, eye, open palm, skull, wing, mask, mirror surface, throne, ring, fissure, light curtain, shadow, geometric structure, spatial cross-section, stage proscenium, abstract symbol, or any other more creative, more topic-representative visual silhouette — with a reasonable layout. Prioritize silhouettes that most amplify the topic's character, form the strongest visual memory hook, and best express epic feel, mystery, poetry, or design sensibility — over the safest, most ordinary, most common container. The core of the image is not to simply stuff the world into some object, but to let the full topic-world grow naturally within, inside, upon, on the border of, or merged with the structure of this primary silhouette — producing a high-order narrative effect of "the topic's universe unfolding attached to a symbolic silhouette". The primary silhouette must be clear, elegant, and recognizable, and must occupy the central place in the composition. Inside or along the border of the silhouette, auto-generate a complete narrative world tightly tied to the topic — content should be rich, full, with clear layers: iconic scenes most representative of the topic; the core architecture or spatial structure; symbolic elements and metaphorical elements; character relationships or traces of civilization; spatial progression from distance to middle ground to foreground; atmospheric layers that carry a sense of destiny and emotional tension; and narrative details like doors, steps, bridges, water surfaces, smoke, paths, light sources, ruins, mechanical structures, natural landscapes, abstract forms, creatures, or props. All elements must unify naturally, with clear primary and secondary hierarchy — as if a complete world were truly gestating within this silhouetted structure, not a simple collage, cropped fill, asset stack, or templated background. The overall composition must carry a strong collector-poster aura and premium design sensibility. The macro structure should be stable; the primary silhouette strong and unambiguous; the inner world should have depth, order, and breathing room; details should be rich but not crowded; content should be full but not chaotic. It is acceptable to add in small-scale figure silhouettes, distant buildings, light columns, doorways, bridges, stairs, colonnades, reflections, skylight, or distant structures to enhance sense of scale, narrative, and epic feel. The overall image should be quiet, grand, distilled, and lingering in aftertaste — not evenly filled, not cheaply busy, not stacked without focus. Style fuses collector-edition film poster composition, high-end narrative visual design, dreamy watercolor texture, and the feel of a paper print. Emphasize paper grain, dry-brush edges, watercolor brushstrokes, slight bleed, aerial perspective, soft mist, localized volumetric light, light cutting through mist, large expanses of negative space, and restrained layout — so the image looks like a premium collector-edition piece crafted by a designer, not a generic AI render. Overall atmosphere: premium, poetic, grand, sacred, nostalgic, quiet, with a sense of legend and storytelling. Colors: the AI auto-decides and matches the most suitable premium palette for the topic — but must stay unified, restrained, quietly beautiful, low-saturation, and refined. No noisy high saturation. No cheap neon. No plasticky digital feel. Palettes may freely move across black-gold-gray, cool blue-gray, foggy white-gray, maroon-red-cream, antique copper, old-paper tones, deep-sea blue, dusk purple, silver-gray, or other systems — but must always serve the topic while maintaining poster-grade aesthetics and overall harmony. Final requirements: first glance — strong topic recognition and silhouette memorability; second glance — a complete, richly rendered narrative world; third glance — still detail and lingering aftertaste. Silhouette choice must be creative and topic-appropriate; avoid repeating safe, common container clichés; prefer silhouette forms with more symbolism, more spatiality, and more design potential. No generic background collage, no awkward cropping, no templated fantasy assets, no game-promo feel, no over-cartoonishness, no over-realism that kills artistic feel, no form over content. If fitting, naturally add a restrained, low-key title, edition number, signature, or seal — to make it feel more like part of a collector-edition poster — but never let them steal the show.
