The Anvil of Forgus originally belonged to Forgus, the founder of the House of Forgus from the Mythsetia Veil. It was eventually passed down to his descendants and currently rests in the hands of Vulcan the Bull, the only living descendant of Forgus. During the Great Purge, the Anvil was taken to the Sanctuary Zone during the House of Forgus' escape where it remained with the family's final descendant, Vulcan.
The Anvil is a special piece of magical equipment that is able to forge any piece of weaponry or equipment as desired by the individual using it. Legend says that it was used to forge all the other sacred relics.
