Temnocelium

== Temnocelium ==
There is a substance so hard that it can only be shaped by the magic of the most powerful artificers. It is so durable that it never degrades, testing the patience of Time itself. Traditional weapons are useless against it; it is easier to put dents in the laws of physics than in its surface. It is the metal that is innocent of death. It is called Temnocelium, and (un)fortunately for the locals, it is created only on Erathes.
Temnocelium is a magical black metal. It can look glossy black, matte black, or silvery-black—steel, but dark. Motes of magical energy orbit objects and artifact creatures made from Temnocelium. The trajectories of the energy motes form glowing streaks around the artifact. Creating Temnocelium to make tools or constructs is an extremely difficult art as the same properties which make the material indestructible requires the artisan to shape the metal at the exact instant it is forged. Once it is set, only a Wish spell can make Temnocelium malleable again.
Temnocelium is an alloy, not mined in its indestructible form. There are five components: Iron, Carbon, Adamantine, Mythrill, and Toven. Iron and carbon provide the underlying crystaline structure of steel; Adamantine gives its extreme hardness; Mythrill contributes its ductility, durability, and corrosion resistance; and Toven allows it to be enchanted, and be strengthened by magic. The process of alloying the metals into Temnocelium is difficult, expensive, time-consuming, and requires rare ingredients, specialized equipment, a ridiculous amount of heat - often provided by a Dracanthacite furnace.
However, although the Temnocelium itself is completely indestructible, the enchantment which turns the components into Temnocelium (that is, which makes it indestructible) is not - it can be weakened (although not by the normal spells which dispel an enchantment). This dispelling is what allows Temnocelium to be reforged. But it requires a Wish spell.
