"The Great Powers are those sorts of...well, the ones who are more than us measly little people. I've only met four." That was rather more Great Powers than most people met, Lydia. "Miss Lambe is one of them, of course, and Wormentongue and the Long Man and the Sea." Hey, Adrian, did the sea murmur for witches to come away, love, come away in your universe? No? You lucky dog. "Although Wormentongue was just the ghost of a Great Power!" And also he totally hadn't almost eaten her! She swore!

"I suppose she was called the Jewel of Propriety because when she was coming into her power she became a sort of...living statue made of amethyst for a time," Lydia explained, for a certain value of 'explaining.' "That made getting her away from Brighton and the Order quite difficult, I can tell you. As the Witch Queen, she has power over the witches of Brighton and can aid them in their endeavors," which some of them were probably not enjoying, considering they had tried to keep her an amethyst statue to use as a magical battery, "but she is quite tied to Brighton itself. She is trying to figure out a way to come and visit me here, and I do hope she can work it out."
