These evolving forms are taking on some kind of magic - almost a form of liquid molybdomancy. The pigment is called Spinel black and is derived from Spinel which is composed of the metals aluminium and magnesium. Traditionally molybdomancy used molten metal as a form of divination. This was a tradition of various cultures, including Finland, Austria, Germany and Switzerland. As these evolving forms continue they seem to be following their own evolutionary journey.
