Crystal is a material that can be forged by a special psionic process to be harder and more sturdy than normal materials. Forging crystal weapons requires special training and a moderate amount of psionic ability. Crystal is not terribly difficult to come by, but is expensive enough both to purchase and make that most often it is created on-demand. Crystal edges are naturally flowing formations and patterns, like frozen ice; sometimes soft, or sometimes jagged.
