Basement Dragon: Photorealistic Encounter

Photorealistic dragon in a damp basement. A colossal dragon coiled around a hoard of rusted chests and glittering gems, scales shimmering in iridescent green and copper. Cracked concrete walls with exposed pipes, hanging cobwebs, and puddles reflecting a flickering overhead bulb. Moody cinematic lighting with volumetric fog, dramatic shadows, and subtle rayleigh scattering. The dragon's amber eyes glow while nostrils emit a wisp of smoke. Emphasize texture: wet scales, gritty concrete, tarnished metal, treasure glinting in the gloom.
