Smog Child

it was once told that a lonely orphan became possessed by a mysterious dark smog-
Thus reborn as the smog child. The villagers feared him however he never hurt anyone nor caused havoc. He would walk the streets
during nightfall and before sunrise. From the rare glimpses the townspeople witnessed, the smog child would always emit a dark smog from his body and soul.
No one knew the smog child's whereabouts. One day he completely vanished from the town and was forgotten.
