Demi-Plane of Dread

The Demi-Plane of Dread, sometimes known as Ravenloft or the Domains of Dread, was unique, similar to the plane that contained the city of Union in that many worlds and planes connected to it but it was still independent of them all. It was once technically part of the Ethereal Plane but was markedly different from the vast majority of that plane. Someone on the demi-plane would be forgiven for thinking that it was made out of some supernatural mist as the stuff bordered every domain and entering the mists could transport one to another location on the demi-plane. These mists occasionally formed on the Material Plane to bring individuals, buildings and even entire countries into the Domains of Dread.
