The Sand God

The Sand God is a dark deity who rose to prominence some time after the Treaty Between Heaven and Hell. The gods were powerless to intervene in his reign of terror since they had forsworn acting in person in the material realm as part of their treaty. Through some long-forgotten magic the Sand God was sealed inside ancient armor, banishing most of his essence and sentience to Limbo, thus limiting his power to the point where he could be contained and sealed in a tomb.
