Grungni

Grungni is the duardin god of mining and smithing, a master of metalcraft and the father of his race, who led the duardin and founded the Iron Karak. Sigmar found him and his brother Grimnir imprisoned on the highest summit of the Iron Mountains and freed them; in return Grungni promised to make whatever the God-King wished, and both brothers joined the Pantheon of Order that governed the realms through the Age of Myth. During the Age of Chaos Grungni forged the Stormcast Eternals, but he does so no longer: relations with Sigmar soured after Grimnir died settling his own debt in battle with the godbeast Vulcatrix.

He also mined the starmetal from which Ghal Maraz was forged and helped Dracothion and Tyrion build the Sigmarabulum. He is one of the duardin Ancestor Gods alongside Grimnir (battle and grudges), Vhulkhaya (brew and gold), Morgrim (engineering), Gazul (the duardin dead), Grednir (gems and artistry) and Thungni (runesmithing).
