Ancient Void Mirror Artifact Poster

Goal: Create a dark fantasy Chinese xianxia artifact poster featuring an ancient imperial treasure mirror called {argument name="artifact name" default="虚空镜"}, majestic and mysterious but not horror-themed.

Canvas: Landscape 4:3 composition, cinematic concept art, high resolution, with the image divided visually into a left text column and a right artifact display. Use a black, charcoal, deep blue, and antique bronze palette with soft cold mist and faint golden highlights.

Layout: On the left, place exactly 5 text elements: 1 large Chinese title at the top and 4 smaller Chinese paragraph blocks beneath it, aligned vertically with generous spacing. On the right, place exactly 1 monumental circular bronze mirror on a stone pedestal, occupying most of the right half of the frame. The mirror stands inside a ruined underground temple or ancient tomb hall, centered on a circular stone platform with broken steps in the foreground.

Text content: Use elegant vertical-feeling but horizontally arranged Chinese typography in pale warm gold. The title should read {argument name="headline text" default="虚空镜"}. The four paragraph blocks should describe the artifact in Chinese, in the style of a mythic encyclopedia entry for an imperial weapon from the novel "Shrouding the Heavens"; keep the text legible, poetic, and solemn, with no extra captions, logos, or watermark.

Subject details: The mirror is a huge circular ancient bronze relic with a thick ornate frame covered in engraved runes, carved beasts, curling cloud motifs, and ritual patterns. At the very top of the frame is a fierce dragon or taotie mask with horns and fangs; on both sides are symmetrical curling decorative handles; at the bottom center is another beast-head ornament above the pedestal. The reflective surface is not a normal reflection but a deep cosmic void: a swirling blue-white galaxy vortex, spiral nebula, stars, and a luminous center, as if looking into spacetime. The artifact should feel like it can illuminate all realms and reveal ancient secrets.

Environment: A vast shadowy stone chamber with towering pillars, carved circular reliefs in the background, wet cracked floors, scattered rubble, shallow water reflections, drifting fog, and beams of cool light from above. Keep the atmosphere ancient, grand, mystical, and awe-inspiring rather than sinister.

Visual style: Ultra-detailed dark fantasy realism, Chinese ancient mythological design, imperial bronze craftsmanship, dramatic chiaroscuro lighting, cinematic depth of field, subtle volumetric haze, sharp ornamental details, high contrast, epic scale. Use {argument name="artifact material" default="blackened antique bronze with worn gold edges"} for the mirror frame and {argument name="cosmic portal color" default="deep blue, silver white, and violet-black"} for the vortex inside the mirror.

Constraints: Include exactly 1 mirror, exactly 1 pedestal, exactly 1 large title, and exactly 4 paragraph blocks. Do not add people, modern objects, neon sci-fi interfaces, comedy elements, blood, skull piles, or overt horror imagery.
