An alluring necromancer commands a soul-rending ritual in a cathedral of shattered obsidian, low-angle perspective amplifying her towering presence amid floating bone shards. Gold-and-black Art Nouveau filigree robes cling to her form, her porcelain-pale face framed by cascading raven hair, eyes blazing with violet necrotic fire—living yet inhumanly perfect. Influenced by Brom’s dark fantasy dynamism and Klimt’s gilded opulence: spectral amber backlighting carves jagged shadows, casting her as both deity and destroyer. Swirling void-smoke merges with glowing crimson runes above her palms. Molten gold bleeds into cracks beneath her feet; a skeletal hand offers a wilted rose at her boots. Hyper-detailed textures: alabaster skin traced with luminous necrotic veins, tarnished silver embroidery, iridescent ectoplasmic mist. Chiaroscuro intensifies opulent decay.
