Pegimala-lunavidicosis

This disease is a common occurance amoung young females. Also known as Lock-Jaw Night-vision, Pegimala-lunavidicosis manifests itself within the condyle and causes an excess production of calcium. This calcium accumulates over time and can cause limited movement of the jaw bone and can even lock this bone into place.
This increased production of calcium also causes deposits in the eye sockets and can grow to such a size that the compression in the socket itself disfigures the eye ball; this disfiguring leads to a stretching of the Iris itself resulting in an increased ability to see in the dark.
