masterpiece, best quality, hyperrealistic photograph, dark fantasy art. A 28-year-old feminine demon stands completely nude in 3/4 view within a chamber of black marble and obsidian. Her skin has the appearance of polished volcanic glass, reflecting the hellish glow of floating embers around her. Intricate patterns of molten gold seem to flow beneath her skin, pulsing with infernal energy. From her temples curve elegant horns of black ivory, inlaid with glowing crimson runes. A powerful tail tipped with a blade-like barb sweeps slowly across the floor behind her. Her hair flows like liquid shadow, moving as if alive, with occasional embers glowing within its depths. One hand rests on a fractured skull throne while the other holds a crystal sphere containing a miniature storm. Her eyes burn with eternal fire, pupils like vertical slits of molten lava. The air around her distorts with heat, and the shadows themselves seem to kneel at her feet. Her expression is one of ancient power and dark amusement, lips curved in a subtle smirk that promises both agony and ecstasy. Shot with dramatic underworld lighting that contrasts the dark sheen of her skin with the intense glow of her golden markings, medium format, 8K resolution.
