Doomsday horror style. A digital artwork depicting a towering mechanical prophet standing amidst the ruins of a devastated metropolis. The figure's body is a fusion of ancient religious robes and corroded machinery, with steam venting from joints and gears visible through torn metal skin. Its head is crowned with a ring of floating holographic symbols, while its eyes emit an eerie blue light. Below, masses of cyber-augmented cultists kneel in the radioactive ash, their bodies marked with glowing circuit patterns. The sky is a perpetual twilight of nuclear winter, with the remnants of skyscrapers jutting like broken teeth against the horizon.
