Genasi, Earth

Elemental earth manifests differently from one individual to the next. Some earth genasi always have bits of dust falling from their bodies and mud clinging to their clothes, never getting clean no matter how often they bathe. Others are as shiny and polished as gemstones, with skin tones of deep brown or black, eyes sparkling like agates. Earth genasi can also have smooth metallic flesh, dull iron skin spotted with rust, a pebbled and rough hide, or even a coating of tiny embedded crystals. The most arresting have fissures in their flesh, from which faint light shines.  
"The following communities are known to the people of Myzelis and recorded in the Journals of Eblin. Realms not listed here have no known populations of these Aethrin large enough to list as communities in their own right."

Gylidder Earth Genasi

  Gylidder Genasi are descended from Inaethri who left Myzelis for the inner planes of Air, Earth, Fire, or Water long before the Mortal Era began. Their ancestors were infused with the essence of those planes and became elementals in their own right, summoned to the material plane for a medley of arcane reasons. Over time, the elementals' essence was transmuted into mortal bloodlines and the Genasi were the result. There is no single commune of elemental Gylidder Earth Genasi, but there are some families well known for their affinity for the element; the Stoneborn of the nomadic Xhogumal, the Obelisk family of Dobkwar (literally descended from the Inaethri Jomrune), and the Shaleren of Hangorfeydd.  

Verberan Earth Genasi

  Stoneborn Genasi: Some of those who are born on the island of Verbera have been influenced by the elements that make it up. These persons, the genasi, are usually associated with the elemental planes. It is unknown whether this is accurate, but what is obvious is that the genasi are as unusual as aasimar, tieflings, and kalashtar. Their skin can be cold and durable like stone or hot to the touch, and they possess certain magical capabilities that make their birthright clear.
