Greyspace is the region of space in the Material Plane that surrounds the distant world of Oerth. Oerth lies at the center of Greyspace and is orbited by its sun and several other worlds.
Greyspace is located within the Radiant Triad, a celestial neighborhood that also encompasses Realmspace and Krynnspace (within which lie the worlds of Toril and Krynn).
