Dumathoin

Dumathoin is a dwarven demigod, the child of Moradin. He is known as the Keeper of Secrets under the Mountain.

In the Arcane Chambers, That Group of Adventurers came across an altar to Dumathoin, covered in greasy goblin handprints. Phranz Mir-Dir-Phukkir magically cleaned the altar, and Dumathoin bestowed him with a temporary boon for doing so.
