Dirmsteel, sometimes known as godsteel or exaltium, and is a special, naturally occuring form of magical steel that is created naturally in rare deposits deep below the earth. The steel is reportedly warped by both Ley Line energy and by a strange magical resonance that reportedly becomes stronger deeper into the earth. While dirmsteel is one of the toughest materials in the known world, the power it emits can be overwhelming for those of weak heart and constitution. Furthermore, forging dirmsteel takes a masterclass smith familiar with magical craftsmanship and capable of surviving the extreme heat necessary to form the steel into a malleable state. Dirmsteel can also only be manipulated by the energy of a living soul, requiring a special tool that matches the resonance of the smith's soul to shape it. In legend, dirmsteel is known as being a material that resists the power of gods themselves.
One of the only known beings capable of forging dirmsteel is the legendary smith Leadbelly Fargus, though due to the dwarf's secretive nature, it is unknown how many works of dirmsteel he managed to create. Once well known example of his work was the reforging of Dragovanes in dirmsteel.
The number of individuals capable of using dirmsteel is slightly higher, yet still low. The ancient demigod-hero Krudain reportedly used chains of dirmsteel to bind the demigod of flames Alurkhet at the dawn of the Age of Iron and Chains, though accounts of this are highly disputed and have been warped by time. A more recent example is King Seamus McHammerface, who had such a force of will that he was capable of wearing an entire suit of armor that had been reforged with dirmsteel. The queen of the Kalhastian Empire, Arenora Valemoon, apparently kept a dirmsteel dagger on her person at all times, and the giant-king Unknown reportedly wielded a mighty hammer of it as well. The most resistant individual to date is likely the hero Tyerjon, who managed to dig down into a deposit of raw dirmsteel and retrieve a chunk with his bare hands.
