Small bluish-grey crystals, the vyord crystals are mined mostly by Duergo Dwarves in the deep reaches of the earth. They are worth 1000gp, on the average, for a good quality stone. Poorer quality stones can fetch only 100-200 gp They are about as hard as rubies, and have smooth textures. Their most potent and mysterious quality, however, is their ability to create invisible lines of force that push away magical energy when in contact with living creatures.
Their anti-magic qualities are activated with the touch of any creature. It immediately creates a crystalline structure around the creature, in which no magical energy can exist. Therefore, a mage in contact with a vyord crystal could not cast any spell, as he could not draw on any magical energy to create the spell. In rare cases, the power of an incredibly perfect crystal sheilds the creature touching it from the effect of spell, but these stones are nearly impossible to create, and it is nigh impossible to simply find a natuarlly occuring stone with such a perfect alignment. Vyord stones also form the force-lines if they are touching metal that is touching a living creature. In this case, it creates a nil-magic bubble around itself, the creature, and all the metal touching it or the creature, and any other creatures touching any affected metal. (The force lines and crystalline structures mentioned in this paragraph are invisible, intangible, and undetectable except for the absence of magical energy.)
Vyord crystals are often used in jewelry, most prominently in the Imperial Crown of Chakha, which has a plum-sized vyord crystal at its apex.
Some sages speculate that that the absence of magical energy around a creature caused by a Vyord crystal may become health hazardous if kept up for a long period of time, but no evidence for or against this has been proven, except for the last (and first) king of Chakha to wear the crown; he went insane a few years after the vyord was added to the crown, which hasn't been worn since. Whether or not it was the magical absence that caused his insanity is unknown, but most vyord-haters site it as their prime example of the dangers of vyord crystals.
