It was just another day in the small town of Millfield, or so everyone thought. But as the sun began to set on that warm summer evening, something strange began to happen. A thick fog started to roll in from the nearby hills, blanketing everything in its path. At first, it was a mere curiosity for the residents of Millfield, but as time passed and the fog refused to dissipate, their curiosity quickly turned into fear. The fog seemed to have a life of its own and with each passing hour it became more menacing - almost as if it were alive.
