Material Plane

The Prime Material Plane is the plane in which Methera and it's surrounding cosmos exist. Creatures capable of multiplanar travel will often refer to it simply as the Prime, differentiating it from the Ethereum and the Twilight, to whose borders it is connected at all points. This is because there is no way for direct travel between Ethereum and Twilight without first passing through the material plane, making it a central point in cosmology.
