The Changelings are believed to have at one point in their history possessed a Great Crystal of their own, the glass of which glows blood red in darkness. According to Changeling mythology, the Changeling Crystal was shattered long ago by Elsene during her battle with Asag.
Shards of the Changeling crystal remain scattered across the world, some recovered as artifacts in fetid feykind swamps, others discovered in the depths of ancient caves. The glass of such crystal is said to reveal the true form of a Changeling when beheld by a Changeling, whereas for all others the glass casts a blurry reflection.
Due to the tremendous numenic power of the Changeling Crystal, all shards resonate with a strange psychic influence that makes them dangerous to possess for extended periods of time.
