Acid Fog

Acid Fog or The Veil is a poisonous gas created by the Mountain Men. It is first shown in Earth Kills. The Grounders have a warning system where they blow a horn to alert others of the fog.

While listening to a radio transmission from the Mountain Men, Raven and Abby discover that the Mountain Men have been deploying the fog as a weapon, which they refer to as the Veil.
