Vordark Crystals are mysterious items that seek to consume vorsys, or magical energy. This is because they are the scorched blood of a vorwyrm, which is lacking vorsys. They were created when the vordragon Gyva drew the blood of the vorwyrm Dekilia and scorched it with fire. These crystals rained down upon the earth. The Eari used Vordark Crystals to create the Eari Stones, which the Tal Calar wielded during the Great Purge.
