towering biomechanical priestess creature, elegant yet terrifying, with elongated limbs and a slender exposed muscle torso wrapped in white cracked exoskeletal armor. head covered by a massive crescent-shaped blade helmet, smooth ivory surface with fissures, forming a mask that hides the face. long razor-sharp scythe-like appendages extending from shoulders, delicate multi-jointed fingers ending in needle-like claws. flowing red ceremonial cloth draped elegantly around the hips and arms, contrasting with pale bone and raw crimson muscle. background of a pale cathedral-like void, soft glowing particles drifting in the air, ethereal light filtering from above, hazy and dreamlike atmosphere. composition emphasizing alien grace, ritualistic posture, and unsettling beauty. high-detail dark sci-fi fantasy digital painting, painterly textures, muted color palette with strong red contrast, atmospheric lighting, in the style of Mohrbacher, Dorota Petrowiak, and high-end concept art.
