The Infernal Forge was a forge made by Sartan, for His Infernal Knights during their residency within the Iron Citadel, in Ashtan. The Infernal Forge became the property of the City of Ashtan, during the ousting of the Infernals in 300 A.F.
The Infernal Forge remained the property of the City of Ashtan, until the Maldaathi Knights, aided by the City of Mhaldor, launched a surprise attack within Ashtan, reclaiming the artifact once more to the true lineage of the Infernal Knights. From that point on the Infernal Forge was stored within a secret passageway, beneath the Spire of Annihilation.
