They stepped out—three adolescents, skeletal wings arching, canine bodies corded with muscle the color of old blood under velvet-black skin. White eyes, blind to anything but what death had taught them to see. The Thestral-Hound Hybrids moved like bad memories and perfect weapons.
Hermione’s voice carried. “Umbrahounds, Nott-Pattern,” she announced. “Named for Theodore Nott—first volunteer to drill their leash-whistles and survive a breach. Flight-capable at maturity. Two riders per mount. Silent, obedient to command tokens, immune to fear.”

The prisoner moved in three fewer pieces than he had been meant to, and nothing in the room pretended to be surprised.
