Session 29: Going with the Flow

Earth elementals live on the Elemental Plane of Earth, which they share with jabali (Earth elemental genies), crystal dragons, and a host of other elemental creatures.
Little is known of what earth elementals do on their home plane. Unlike most of the plane's other inhabitants, they avoid the labyrinthine cavern system that winds throughout the plane in favor of staying in the deep earth. They interact with the plane's other inhabitants only when jabalis or others attempt to mine a valuable vein of ore or crystal in which the elementals live, and such encounters rarely end peacefully.
When earth elementals do end up in the Universe, usually through summoning, they tend to congregate in the depths of the earth and are more likely to be encountered in the Darklands than the surface of Golarion.
