"Instead of metal strips, this armor uses wyvern scales bound to a chain backing by means of a magical fire. The resulting armor is ash grey in color and more flexible than standard splint mail. A ranger, Usher Skacan. made this armor after slaying several wyverns that were killing all the deer and elk in his forest."
