About the Inner Planes
Rings of the elements are what make up the Inner Planes. They are the building blocks of the Prime Material Plane. And, following the Rule of Threes, there are three categories within the Inner Planes: the major elementals, the paraelementals, and the quasielementals.
The Elemental Planes
The Elemental Planes are, how can a basher describe it, “extremely single-minded”. Each plane is based around it’s element to the near exclusion of everything else. For most non-elemental creatures, travel and survival on the Elemental Planes is not to be taken lightly.
The Paraelemental Planes
These planes exist where Earth, Air, FIre, and Water merge into each other.
The Quasielemental Planes
These planes are created at the borders of the Positive and Negative Planes, between the basic elements of Earth, Air, Fire, and Water.
