Highly detailed black and white surreal biomechanical illustration in H.R. Giger style. Central core of weathered metallic biomechanical fusion merging organic sinewy tissue, rib structures, vertebrae, tendons with intricate industrial pipes, segmented ribbed tubes, cables, pistons, corroded gunmetal machinery in dark silver gray tones. Symmetrical complex tendrils, flexible organic-mechanical appendages, insectoid limbs, serpentine veins wrapping vast structure. Dark cathedral necropolis atmosphere with occult architecture, infernal fog, oppressive horror, airbrushed monochrome gradients, smooth curves contrasting sharp mechanical decay, ultra-detailed surreal industrial surrealism. Photorealistic textures, high contrast volumetric lighting, cinematic depth.
