Surreal volcanic island floating in infinite obsidian void, liquid chrome mercury rivers carving through jagged obsidian cliffs, molten gold and copper veins pulsating beneath crystalline rock surface, iridescent oil-on-water rainbow oxidation spreading across metallic terrain like living skin, razor-sharp volcanic peaks frozen mid-eruption with suspended metallic ash particles, dramatic volumetric lighting piercing through chrome clouds, macro detail of crystalline obsidian edges catching prismatic reflections, hyperrealistic 8k render, deep void background with scattered ember dust particles
