It is a place of hidden riches. It is a wall against all foes. It is a grave for the greedy.
The Elemental Plane of Earth is a solid place made of ￼￼rock, soil, and stone. The unwary and unprepared traveler may find himself entombed within this vast solidity of material and have his life crushed into nothingness, his powdered remains a warning to any foolish enough to follow.
Despite its solid, unyielding nature, the Elemental Plane of Earth is varied in its consistency, ranging from relatively soft soil to veins of heavier and more valuable metal. Striations of granite, volcanic rock, and marble interweave with brittle crystal and soft, crumbling chalks and sandstones. Thin veins of gemstones, rough and huge, can be found within the plane, and these unpolished jewels often lead the greedy to this plane in the hopes of picking them up with minimal effort. Such prospectors often meet their match in the natives of the Elemental Plane of Earth, who feel extremely attached (sometimes literally) to parts of their home.
The Elemental Plane of Earth is a place hostile to life from the Material Plane, but unlike the Elemental Plane of Fire, it is not actively hostile. Rather, it is uncaring, unconcerned about the motes of life that move through it and around it. It is solid stone, as patient as the earth itself. And it has all the time in the universe.
