Mindful of what it said in Hogwarts, A History about the school’s wards against Apparition, Hermione went to extra effort to enhance her summoning on this occasion, just in case. With a stick of chalk she drew her usual circle within an equilateral triangle on the bathroom tiles. It was as large as she could possibly make it, and broken on one edge so the demons could depart it freely. She wrote all her demons’ names, each separated with a handful of runes, in tiny letters all around the circumference. She cut one of the fingers on her left hand very gingerly, and flicked the blood across the circle. Crookshanks, as if knowing his role without being told, held the struggling mouse down with his clawed paws. With a quiet sigh of regret at the necessity, Hermione winced and quickly chopped off the mouse’s head with her sharpened silver athame, and then swapped the knife out for her unofficial and much-preferred homemade oak and vine wand. It took a while to quietly whisper all her friends’ names, but eventually she was done and the circle lit up with flickering green and red flames, and they all arrived in a shimmer of heat and light. Most of them arrived quietly, though with an atypical and odd popping sound like a bursting balloon.
