黑曜石王座奇幻书封

一幅竖版史诗奇幻小说封面插画，标准6×9英寸平装书尺寸，考虑书脊出血。主体是一位孤独的铠甲人物，站在破碎的黑曜石宝座台基顶端，背对一道撕裂天空的竖向炽白金光裂缝——仿佛苍穹本身正在分裂。人物身着火山玻璃碎片组成的板甲，每片从不同角度捕捉裂缝之光，折射出七彩反光。身后的宝座巨大而不对称，一侧扶手呈弯曲爪形，另一侧已坍塌成碎石，漆黑火山岩雕刻，岩脉中岩浆光芒勾勒出符文。前景是碎剑与冰霜覆盖的石板路。背景是半埋于冰川的坍塌尖塔，顶端被地下岩浆染成橙色。天空占上部三分之一，裂缝居中，两侧是灰白碎月残骸。光效：裂缝强侧光漂白人物左肩与头冠，冷蓝环境光填充冰原前景，岩浆裂缝发出深橙色。配色：黑曜石黑、炽白金、深橙岩浆、冰川蓝、骨白。画面顶部15%留深色色带，供金色衬线字体标题使用。不渲染任何实际文字。

An epic fantasy novel cover illustration in portrait format, designed to fill a standard 6x9 inch paperback cover with spine bleed in mind. The central subject is a lone armored figure standing atop a fractured obsidian throne dais, silhouetted against a sky torn open by a vertical crack of blazing white-gold light — as if the heavens themselves are splitting. The figure wears plate armor assembled from volcanic glass shards, each piece catching a different angle of the rift light, casting prismatic reflections across surrounding stone. The throne behind the figure is enormous and asymmetric — one arm ending in a curled claw, the other collapsed into rubble — carved from jet-black volcanic rock with veins of glowing magma tracing runes into its surface. The foreground is a shattered courtyard strewn with broken swords and frost-crusted stone pavers, suggesting a battle just ended. The horizon is a line of collapsed spires half-buried in glacial ice, their tops glowing orange from subsurface lava light. The sky fills the top third: a void-black canopy with the great rift dominating the center, flanked by debris of shattered moons in pale grey and bone white. Lighting is theatrical: hard rim-light from the rift bleaches the figure's left shoulder and crown; cold blue ambient fills the ice foreground; deep orange emanates from magma cracks in the throne. Color palette: obsidian black, blazing gold-white, deep magma orange, glacial blue, bone. Typography placeholder: leave the top 15% of the image as a darker band suitable for a title in gold serif type. No actual text rendered.
