Thrakûr-Gundak, known in Common as the Mantle of the First Forge, was an Epochal Artifact that resembled a statue; it appeared to be an inert Golem of gold, Mithral, and Adamantine, bearing a mighty warhammer and shield. In actuality, however, the artifact was an accessible set of armor. Traditionally kept in the titular throne of Brazenthrone, the armor was Dwarf-sized, and its back opened to fit the sovereign of the nation inside, morphing around the wearer like a second set of skin. Once the armor was "donned", the Mantle of the First Forge acted autonomously, responding to the thoughts and wishes of the creature inside.
Perhaps the greatest piece of protection ever designed, Thrakûr-Gundak contained a constantly-churning heat greater than any forge. Many dwarven priests believed that the armor was crafted by a diviner power to ensure they would never be defeated in battle. However, lorekeepers point to records actually indicating that the Mantle was actually a gift from the Azure Paragon, an ancient Wizarding group that channeled the armor with a Leyline to the Para-Realm of Magma. The resultant artifact was believed to contain more latent magic than any had been seen by dwarf-kind.
Those who donned Thrakûr-Gundak became practically indefatigable and unkillable, but they were not only protected by the sheer energy within; they were also able to deliver hammerswings that could break the earth. It was said that a single blow from a creature within the Mantle was strong enough to melt mountains, boil lakes, or crack open divides that spanned continents. To ensure the structural safety of Brazenthrone, the armor was never used within the halls, lest the city itself be sundered.
