Paraelemental Plane of Magma

Bordering the two inhospitable planes of Earth and Fire, it shouldn't be a surprise to any traveler that the Paraelemental Plane of Magma' is an unpleasant place. It's easiest to imagine it as spewing out from the plane of Fire, whose leaping flames die down to a hellish glow and then spread in an ever-cooling mass to the plane of Earth. The surface constantly churns and shifts as the scabrous, hardening chunks are churned back into the molten flow. Near the plane of Fire, this churning landscape bursts with occasional geysers of cryoplastic flow, lava that splatters nearby. Closer to the plane of Earth float pillars of solid rock, borne away by the searing tide.

Note: The Paraelemental Plane of Magma originally appeared in this form in the Planescape AD&D campaign setting from TSR. Its use here is for the purposes of providing context for the campaign only.
