Dormium

Dormium is a rare mineral found mainly on the Elemental Plane of Earth. Once rarely found in the great plains of the Kelstaad, it was considered a delicacy by the Tash'la people. After a deal was struck with Elemental Earth, the mineral was consumed in large quantities by the tribes, which in time would cause crystalline growths to sprout from their joints and skulls, affording them a unique resilience and heightened fortitude.
