Archives of Nethys: Oread
The Plane of Earth's influence runs through an oread's family, most often from a shaitan or crystal dragon ancestor. Oreads tend to be stoic, steadfast, and dependable, but they contain depths not seen on the surface.
Oreads can be slow to reveal their true selves, or perhaps more accurately, have enough depth and mystery inherent to their beings that they can reveal new and unexpected facets of themselves every day. They usually feel that they personify certain aspects of earth, stone, or other sediments or minerals, such as a cliff's tenacious resilience against erosion, the generosity and nourishment of fertile soil, or the versatile utility of metal and stone.
Oreads born with a special connection to a specific subset of elemental earth, such as crystal, dust, or mud, might have an oread lineage. A lineage can be inherited along a family bloodline, or it can manifest spontaneously in oread children. They can be caused by where an oread's ancestors lived, frequently seen in dustsoul oreads, many of whom are born in a desert or to a family that has farmed for generations. Lineages can also be the result of specific planar heritages. Gemsoul oreads often have a crystal dragon in their lineage, and miresoul oreads descend from the more sodden creatures of elemental earth.
