Material Plane

The Material Plane is where most of the mortal creatures live and is a general term for any of the normal worlds, such as Eberron, Athas, Greyhawk, or Abeir-Toril. Ravenloft is outside the Material Plane on its own demi-plane, known as The Plane of Dread and is said to originally be made up of pieces stolen from other Material Plane locations. Whether these stolen pieces are copies or the actual location is unknown.
