The rise and success of the Judges came from the discovery, a hundred years before, of the Black Crystal of Illian. When the mining Guild representative was shown the first piece of the perfectly formed crystal brought to the surface. He had no idea, no way of knowing, the impact this unusual crystal would have then and in the future.
It would take a further decade before the truth and ultimate significance of these tiny structures would become known to the Law Guild. And when it dawned on the Imperium Council just what it was the Miners Guild had found, there was no going back.
The Crystals sang.
