The Elder Elemental Eye is an artifice designed by Tharizdun to deceive primordials and mortals into offering power to him. Followers of the Elder Elemental Eye unwittingly aid in the effort to release the Chained God from his divine prison. A group of primordials including Imix and Ogremoch heed the orders of the Elder Elemental Eye, not realizing the dark entity they serve is in fact the Chained God.
During the Dawn War, the gods hunted down the primordials and destroyed them one by one. Few primordials were willing to work together against the gods. However, a small number of primordials, including Imix and Ogremoch, managed to briefly set aside their differences under the auspices of an entity called the Elder Elemental Eye. These primordials, which became known as the Elemental Princes, believed the Elder Elemental Eye was the first of the primordials.
...
From his prison, Tharizdun has little influence on the planes and must depend on his servants to carry out his schemes. Thus, it falls to the Elemental Princes to spread the dark god's influence and expand his power. The Elemental Princes still believe that the Elder Elemental Eye is an ancient primordial. They continue to try to free the entity, but their old rivalries and grudges prevent them from fully working together.
