A substance called Chardalyne found only in Icewind Dale has been turning up, first seen worn around the necks of Cultists, in the hands of Duergar, and in the Defiled Figurehead stored in Easthaven.
This substance, despite its’ crystaline nature, is pliable and workable as a metal, and is in fact easier and stronger than steel. It also readily accepts magical enchantment, including efforts to consecrate or desecrate with extra planar influences.
