Dumathoin

Dumathoin, pronounced (doo-muh-thoe-in), is the patron of Shield dwarves, and the dwarf deity of mining and underground exploration and is known as the Keeper of Secrets Under the Mountain. He is also the protector of the dwarven dead. His holy symbol is a cut, faceted gem inside of a mountain.

Followers
Dumathoin's clerics, known as the talhund ("hidden gifts") protect mines from disrespectful profiteers as well as seek out new veins and gem deposits. They also supervise all mining activities to ensure that the proper respect is paid to the mountain and produce new stratagem and combat techniques for fighting the many Underdark creatures exhumed during excavation.

Dumathoin is said to have specially blessed the urdunnir dwarves, and provides them with the gems they need to live.
