The battlefield of Medusa under a raging electrical storm — black clouds split by constant lightning, metallic mountains and fortress-industrial structures in the distance. Foreground: a massive Iron Hands Space Marine in heavy, battle-worn black power armor, standing like an unbreakable machine. His body is heavily augmented — visible cybernetic limbs, mechanical spine, cables, pistons, glowing red optics replacing one eye. His face is partially exposed, pale and emotionless, fused with machinery. One arm is a full servo-claw, the other holds a brutal bolter or mechanized weapon. Around him — advancing formation of Iron Hands and Skitarii: soldiers with mechanical limbs, glowing optics, robes mixed with armor, moving in perfect synchronization like a machine system. Some are connected by cables, data-streams faintly visible between them. Midground: a Techmarine / Librarian hybrid figure — hooded, surrounded by floating servo-skulls and mechanical tendrils, subtle warp-energy mixed with data-streams, as if controlling both machine and reality. Background: war in progress — explosions, artillery fire, enemy silhouettes crushed under relentless advance. Giant industrial constructs and war engines moving through smoke. Ultra detailed, hyper realistic, cinematic composition, sharp focus, 8k, no blur, no fantasy aesthetics, no organic softness.
