Plane of Earth
The Elemental Plane of Earth was an Inner Plane or Elemental Plane of the Great Wheel cosmology and the World Tree cosmology models. After the Spellplague, the Elemental Plane of Earth collapsed into the Elemental Chaos, mixing with all the other Inner Planes. Earth is one of the four elements and two energies that make up the known universe and therefore of keen interest to cosmologists. The abundance of large gems and huge ore deposits lured many greedy prospectors to brave the significant dangers of this plane.
The Elemental Plane of Earth was an infinite expanse of solid matter pockmarked by bubbles of other elements and riddled with fissures and tunnels created by burrowing creatures or the occasional small mining operation. Ensconced in a few of these pockets were trading outposts and the rare hidden wizard fortress. Solid does not imply stationary: the substances of this plane were constantly moving in a slow, grinding motion punctuated by earthquakes from small tremors to massively violent upheavals. Open spaces were gradually filled by the relentless shifting (or marauding earth elementals) unless action was taken to prevent it. Air could be found in scattered pockets but unbreathable gasses were also present—unprepared travelers lucky enough to arrive in a cavern might slowly asphyxiate while the unlucky quickly suffocated by being buried alive. Other pockets of magma, water, ooze, dust, or ash were particularly dangerous for miners if they accidentally breached one of these. No light existed in the Plane of Earth except for rare luminous gems buried in the crushing darkness. Travelers able to pass through stone were effectively blind unless they used magic such as a ring of x-ray vision, or until their eyes reached an open space where darkvision could operate or a source of light could be produced. Hearing was actually enhanced while encased in earth, to the point where travelers could detect any movement through the rock within a certain radius of their position.
As described by the Great Wheel model, the solid earth changed in proximity to the para- and quasi-elemental planes. A native guide was necessary to find these border regions and each had their own dangers. Near the Plane of Ooze, more water was present and the rock gradually lost cohesion. Approaching the Plane of Magma the temperature rose until the rock glowed with heat and became viscous. Proximity to the Negative Material plane dessicated the earth and caused it to crumble to dust. Toward the Positive Material plane, veins of ore, crystal, and gems became richer and more prevalent, finally crossing the border to the quasi-elemental plane of Minerals.
Every type of rock, soil, mineral, metal ore, sand, and dirt could be found here in abundance, ranging from talc soft to marble tough to diamond hard. Mining operations tended to be small and short-lived because the movement of the substance of the plane and intense gravity caused cave-ins, and the native population defended their territory and/or food supply. In addition, there was the unusual problem of where to put the discarded mine tailings. The dao were the only people known to successfully manage large continuous mining operations in the Plane of Earth. They did this in the Great Dismal Delve mercilessly using slave labor to dig and repair earthquake damage.
