Urugan

Urugan, the XXXXX, XXXXXXXX, is one of the two sons of Kordan and is in turn the father of the dwarven race, which he created. He is the primary (usually only) god worshiped by the dwarves, with the exception of the depraved Derro and Duergar. His arch-foe is his brother god, Korgul, father of the orcish race. Legend tells that Kordan created Urugan to work his mighty chthonic forges in the ancient days when Urva was still unformed.
His name is sometimes also rendered Uragan, or Urudan or Uradan due to the similarity of the hard 'g' and emphatic 'd' phonemes in certain dwarven dialects.
