Blackstone (Ducateon destruction in the realms)

Steel Realms

Ducateon make a habit of rooting out and destroying Blackstone. It is mined, crushed, powdered and scattered (even thrown into lava when it can be), and used in quench ponds to create black weapons (it absorbs the darkness – no other effect). The Ducateons see it as the ultimate essence of chaos and their orderly nature drives them to destroy it. The process is always overseen by the priests of Him.
