The Underlands of the Steel Realms are the collection of of inhabited underground lands and places that are not part of the Ducateon or Dwarven “Holt” system. They represent corruptions, twistings, and odd effects from several powerful sources. They do not share much in the way of properties or encounters, other than being underground. It is thought that perhaps the Greenthorne Forest was one of the first places to discover an area of Underlands.
