Inner Planes
The Inner Planes are reached from the Prime Material Plane through the Ethereal Plane. Also called the Elemental Planes are regions of primary forces; the building blocks of the universe. The Inner Planes include the elemental planes of Earth?, Air?, Water and Fire? as well as the Positive Energy? and Negative Energy? planes.
Between the elemental planes are regions of mixed elemental force known as the para-elemental planes; between the elemental planes and the Positive Energy? and Negative Energy? planes are regions known as the quasi-elemental planes. In general all of these planes are hostile to non-elemental life and travel within them is recommended only to those who are prepared. The Inner Planes are not aligned in the same manner as the Outer Planes, rather they are indifferent to the affairs of other sentient beings.
