The Rolyn Crystal is a magical artifact crafted from the raw power of the positive energy plane. It was create to help heal the sick and injured, but it seems to have left a swath of destruction in its wake. Its original creators were all killed when the crystal was formed, so powerful was the energy it put off. The crystal was sheathed in a dampening field to protect those who would use it. It was lost with the fall of the Asrathi civilization.
