A dense, suffocating smog blankets the urban landscape, transforming the bustling city into an ethereal, muted realm. Buildings fade into shadowy silhouettes as the thick haze diffuses natural light, casting an eerie and somber ambiance. The once vibrant skyline becomes obscured, with only the faintest outlines of structures visible through the oppressive fog. The acrid scent of pollutants hangs in the air, assaulting the senses and contributing to an unsettling atmosphere. Pedestrians navigate the streets cautiously, their figures shrouded in the murky veil, creating an otherworldly and disconcerting scene in the heart of the metropolis.
