Worshipers
Dumathoin's clerics, known as the Talhund, 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 produced new stratagem and combat techniques for fighting the many Underdark creatures exhumed during excavation.
