A cinematic digital painting of a divine cybernetic priestess. She wears flowing black silk robes with gold embroidery, blending traditional Eastern aesthetics with gothic armor. Her skin is marble-white with intricate mechanical joints visible. Emerging from her back are eight sharp, obsidian-black arachnid limbs that frame her like a halo. She holds a heavy, ancient brass grimoire while her other hand weaves a glowing golden holographic mandala. Her eyes are a piercing, unnatural icy blue. The background features a blood-red sun and weathered parchment textures with faded calligraphy. Lighting is dramatic and high-contrast.
