Witches, Wizards, and Vamps learn about the Mistress and Her Omen (WTM)
5 parts Ongoing Chaos erupts when the three kings of the vampires appear in the Great Hall of Hogwarts. Aro was giggling at his granddaughter's startled expression, Caius was grumbling, and Marcus had a headache from his gift. Then the Cullens drop in, some complaining some just there. A few more members of the wizarding world stroll in and someone appears to show them the future of the wizarding and vampire worlds.
