While endless adventure awaits out in the game—there are other worlds beyond these—other continents, other planets, other galaxies. Yet even beyond this existence of countless planets exist more worlds—entirely different dimensions of reality known as the planes of existence. Except for rare linking points that allow travel between them, each plane is effectively its own universe with its own natural laws. Collectively, the entirety of these other dimensions and planes is known as the Great Beyond.
Although the number of planes is limited only by imagination, they can all be categorized into five general types: the Material Plane, the transitive planes, the Inner Planes, the Outer Planes, and the countless demiplanes.
