The Danger Fog is only found in the really abandoned spaces of the Ethereal Plane, the places that are reflections of empty places in the True Plane itself. Here, the Danger Fog prowls, seeking to attack unwary travelers and consume them to sate its unending hunger.

Danger Fogs come in many sizes, from tiny tendrils of hazardous mist to enormous cloudbanks that roll along like self-contained storms.

Danger Fogs cannot manifest themselves in the True World, as they are not dual-natured and can exist solely on the Ethereal Plane.
