Grumbar the Earthlord

Out of her motherly creation, the Primordial Mother birthed a son to master the element of Earth. His name was Gorm, the master of stone and matter, and he resided in Terra, the Plane of Earth. Gorm spent his life in service of Anum, craftings rocks, soils and minerals to seed through his brother's world.
Gorm is said to have laid to rest in an impenetrable fortress deep within the centre of the grinding, ever shifting rock plates of Terra, gifting his energy to all that is material upon the prime material plane
