The Mithral Forge is the old forge used by the Dragonlords in the First War.
It was run by Clan Hammer until they were driven out by a monster sent by Lutheria; however, with the help of the Oracle's Chosen, they have recently reclaimed it.
The God Volkan currently resides here, working to make things for the heroes to help them on their journey.
Until recently, Forgekeeper was also trapped here but was freed by Braz during a fight with a Cerberus.
