Teredar The Mountain is the Elemental Spirit and God of Earth, and the prime deity of the Sarai Empire. As the physical manifestation of the earth that formed during the forging of the world, he is a Primordial.
Teredar is one of the few Elemental Spirits to physically appear in the story in his true form. He is a utterly titanic ox made of stone, and is, quite literally, the size of a mountain. In order to save Price, Tara climbed the mighty Earth God to reach the great obelisks that have grown out of his back, each representing the Elementals of Earth. This took her over a day of almost nonstop climbing.
