• Hogwarts students struggled with holiday homework as professors insisted their own subjects deserved hours of daily study, while Harley was exempt from homework and exams as a tournament champion.

Harley discovered the creatures’ deaths were feeding the magic and eroding her, but she secretly redirected the gray mist into a ring and an Invisibility Cloak as the Death Eaters watched the slaughter.

• Harley questioned Voldemort after she easily defeated his first group of Werewolves and Goblins, and he summoned stronger forces led by Fenrir Greyback.
