There was a great emptiness. The villagers dug a deep hole to return Theo to the belly of the earth. As the grave was being dug, Ion noticed two strange discolourations in the exposed soil. One was black and the other was red.
He took samples of both of these rocks back to his cave and began experimenting with them. In his fire, the black rock burned with an intensity he had never seen before. The red rock melted and formed into a very tough lump. Ion realised he'd come upon the perfect material to create the wonderful machines he had been dreaming about.
