Iron Fog is an infamous location ruled by the Brass Herald[1]. It is known for its repository of machines and mechanical contraptions.[2] It is only known to Mireska, indicating that it may be associated with the Fae race and Revtel. Mireska notes that horrible things are done to people in Iron Fog, describing the place in a way similar to how one would describe a prison or experimental laboratory.[3]
