Other native creatures look like rough statues of Material Plane animals and monsters, or are animated crystalline forms of resembling these creatures. There are also alien-looking creatures like khargra, xorn and xaren with a taste for metal. All natives of the plane and creatures with an earth-affinity can move through the plane like a fish through water, with rocks flowing around them and closing back up again, leaving no tunnel.
DescriptionThe Elemental Plane of Earth is an infinite expanse of solid matter sometimes interrupted 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 are trading outposts and the rare hidden wizard fortress. Solid does not imply stationary: the substances of this plane are constantly moving in a slow, grinding motion punctuated by earthquakes from small tremors to massively violent upheavals. No light exists in the Plane of Earth except for rare luminous gems buried in the crushing darkness.
Without protection, a non-native being will be put under tremendous pressure from the surrounding rock and will be without air to breathe or light to see.
Spells can be used to open a temporary portal to this plane, but they can be extremely dangerous unless the destination is previously scouted.
Mining
Even though many tried, the Dao are the only people known to successfully manage large continuous mining operations in the Plane of Earth. Mercilessly using slave labor to dig and quickly repair earthquake damage.
