Planes of the World

Knowledge of Arcana beyond a fairly basic level will include a little general knowledge about the existence of other planes. While the number and kind of planes are potentially infinite, there are a few for which knowledge is fairly common (the elemental planes) and others that little is known about.
Generally access to planes beyond the Material Plane (the "real world") requires powerful magic or some extant connection to the destination plane (such as a planar keystone).
