Elementium is an extremely rare metal, found only in some of the most remote regions of Azeroth. It is believed by archaeologists to have been formed during the prehistoric reign of the Old Gods, in places where there were high concentrations of elemental creatures. In fact, elementium isn’t native to Azeroth, and is found only near high concentrations of elemental creatures because they bring it from the Elemental Plane where it is actually quite common. The unique properties of elementium allow it to absorb and channel elemental forces. Skilled smiths temper elementium in blistering forges, adding to the quality of the item. Elementium is so heavy that to craft armor from it would leave the wearer virtually immobile, so the metal is usually only used to craft weapons.
Massive elementium veins are raised out of the ground wherever the Twilight's Hammer sets up a base. As seen in concept art and in the Twilight Highlands, they build their buildings by raising these veins.
Before the Cataclysm there were various obtainable items associated with elementium, out of which only was crafted by the adventurers. The rest was either created by NPC's from elementium ore or bars they supplied, or appeared to be created at least partially with elementium. Whenever something was made from elementium, it was always quite extraordinary and/or expensive.

With the coming of the Cataclysm however, Elementium has become a much more common material, mostly because of the now easly accessible Elemental Planes, and summoning of the veins by the Twilight's Hammer cultists all around Azeroth. Ever since all craftsmen adapted the use of these materials in various of their plans, schematics, patterns and recipes.
