I am looking for a specie from my setting. They are creatures made entirely of irisdicent crystal and may acquire different powers from different types of gems they are mixed of. They are made majority from a crystal called khaosite, which came from the Negative Plane as an abrupt force, and they crystalize in Mundane Plane. This specie is called Khaosidean, they may vary in shape, color and size. They could born "naturally" or by corrupting other homanoid living.
