Kinamer Galemaul, a dwarf smith in Antonica, spoke of a mythical smithy named Underforge that was said to reside within Stormhold, home of the legendary Knights of Thunder. He said that the Underforge was used to supply the Knights with all of their magical equipment. He doesn't put much faith in the stories from crypt raiders that Stormhold has been discovered, but did ask me to let him know if the Underforge does exist.
