Sky Iron
Essence: air
Rarely, lumps of pure iron is found that appear to have fallen from the sky. The lumps fall more often in mountainous terrain, or at least that is where it is easiest to find. This dark, almost black, form of iron is very hard to forge. Only the dwarven smiths of the mountain tribes have mastered the methods for shaping it into some ome of the sharpest blades in existence. Items made from sky iron are icy cold to the touch, even to the point of frosting up on a warm summer day. The ancient heirloom of the Grungiburgi tribe, the Runewarden, is made from sky iron.
Sky iron costs about 2500gp per pound.
