Lightforge iron

Lightforge Iron is an exceptionally light and flexible metal highly sought after by paladins and templars of all types. According to legend, the ore is formed when touched by the Holy Light. Logically, then, the material is divinely intended for use against the forces of darkness. Although the truth of this is not known, lightforge iron definitely seems to be blessed by some higher power, though it is not inherently good or evil. Even demons have been known to use the material, often out of spite.

Lightforge iron is almost never found deep within the earth. Instead, it appears in clusters of ordinary iron that find their way to the surface during earthquakes or eruptions. Sometimes the ore bubbles up from underground streams or gas pockets that erupt in swamps or moors. This tendency only lends credence to the myriad lightforge iron legends. Deposits have been seen all over the face of Azeroth, but most commonly appear in Dustwallow Marsh, Desolace and the Searing Gorge.

Items crafted of lightforge iron are unnaturally shiny. They gleam brightly in ordinary light, and seem to take on an unnatural radiance when exposed to the full glare of the sun. Even when dirty or dusty they still somehow seem regal in nature. Crafting lightforge iron requires an exceptionally clean environment, almost as though the material expects to be handled in a manner befitting its divine status. The ore must also be precisely purified, or the resulting item will quickly fracture wherever any impurities lie. Most smiths simply do not have the patience to work with such a temperamental material.

Weapons crafted of lightforge iron gather up ambient light and throw it back in an unnatural shine, producing light equal to that of a torch at all times, except in total darkness.
