Grumbar

Grumbar, or the Earthlord, was the elemental embodiment of earth. He was one of the four elemental deities worshiped in Cerillia. Grumbar, like the other elemental deities (except Kossuth) had a minimum of followers in Cerillia, and he cared little indeed for most of those worshipers, as his power came from the many elemental devotees in both the Underdark and the Elemental Plane of Earth. It was recently uncovered in the wake of the Spellplague that Grumbar was not a proper deity at all, but rather a primordial. Nonetheless, he retained worshipers and had power equivalent to that of a god.
