It is believed that the molten balls of ore that Kallex hurled to the surface of Isekai to create the Metallic Dragons were nothing more than barely shaped lumps, but this is far from the truth. Bathed in the Dragon God's fire, the ores turned into beautiful eggs that were breathtaking gemstones.   Mithril Dragons are hailed as having the most beautiful egg, the molten white or blue glass core surrounded by delicate renditions of the scales that normally cover the Dragon's neck.
