Deep dwarves (AKA Urdunnir dwarf) are a long lost offshoot dwarf race.
Lead by Gold lords, this race is very similar to the gold dwarf. They have extreme powers to shape metal. They are always living in clans.
A common deep dwarf attire is one piece armor that is heavy. They may possibly wear robes.
Dwarven myth states that deep dwarves worship a god named Dumathoin
