> Professor McGonagall stood up and moved over to the wall behind her desk, which held a polished wooden board. "There are many reasons why Transfiguration is dangerous, but one reason stands above all the rest." She produced a short quill with a thick end, and used it to sketch letters in red; which she then underlined, using the same marker, in blue:
> Professor McGonagall took a small chunk of wood out of her pocket. With a tap of her wand it became a glass ball. Then she said "Crystferrium!" and the glass ball became a steel ball. She tapped it with her wand one last time and the steel ball became a piece of wood once more. "Crystferrium transforms a subject of solid glass into a similarly shaped target of solid steel. It cannot do the reverse, nor can it transform a desk into a pig. The most general form of Transfiguration - free Transfiguration, which you will be learning here - is capable of transforming any subject into any target, at least so far as physical form is concerned. For this reason, free Transfiguration must be done wordlessly. Using Charms would require different words for every different transformation between subject and target."
> You will protest that you were trying to help all of Hogwarts, a much more important goal worthy of great risks. That is a lie. If you had been -"
> Harry paused, still holding the twig, the mate of the twig he had snapped what seemed like two weeks ago. He was feeling a sudden reluctance; his brain seemed to have learned the rule, by some purely neural process of operant conditioning, that Snapping Twigs Is A Bad Idea.
> All he had to do was step forward and touch the phoenix's talons, and it would take him where he needed to be, where he kept thinking he ought to be, down into the central pit of Azkaban. Harry could see the image in his mind, shining with unbearable clarity, the image of himself suddenly smiling with joyous release as he threw all his fears away and chose -
> "Students serving detention," Filch said, loudly. "They're to help you search the Forest for… whatever's been eating 'em."
> Hagrid seized Draco and Tracey and hoisted them off the path behind a towering oak. He pulled out a bolt and fitted it into his crossbow, raising it, ready to fire. The three of them listened. Something was slithering over dead leaves nearby: it sounded like a cloak trailing along the ground. Hagrid was squinting up the dark path, but after a few seconds, the sound faded away.
> Draco and Tracey stood looking at each other, until they heard nothing but the rustling of leaves around them. Tracey looked scared, but trying to hide it. Draco was feeling more annoyed than anything else. Apparently Rubeus Hagrid, when he had formed his plans for tonight, had not spent even five seconds visualizing the consequences if something actually went wrong.
> "No, you numbskull!" yelled Draco, plunging after her. The sound had been so eerie that Draco wasn't certain where it came from - but he thought that Tracey Davis might, in fact, be running straight toward the source of that eerie scream.
> Harry had been studying Obliviations, these last couple of weeks - though he couldn't have helped cast the spells, unless he was willing to exhaust himself almost completely, and for some reason they wanted an Auror to lose every single life memory involving the color blue. But Harry had some idea, now, of the concentration which the far more difficult False Memory Charm entailed. You had to try to live the other person's entire life inside your own head, at least if you wanted to create the False Memories with less than a sixteen-to-one slowdown as you separately crafted sixteen major tracks of memory. It might have been quiet, there might have been no outward sign; but Harry knew something of the difficulties now, and he knew to be impressed.
> "Ah," Professor Quirrell said. "As to that…" The man hesitated. "I was drinking the blood of unicorns, not eating them. The missing flesh, the ragged marks upon the body - those were to obscure the case, to make it seem like some other predator. The use of unicorn's blood is too well-known."
> Harry had been turning over Trelawney's prophecy in his mind, wondering if maybe the true Dark Lord had nothing to do with Lord Voldemort at all. Born to those who have thrice defied him seemed to strongly invoke the Peverell brothers and the three Deathly Hallows - though Harry didn't exactly see how Death could have marked him as an equal, which seemed to imply some sort of deliberate action on Death's part.
> This alone is the true Enemy, Harry thought. After this will come Professor McGonagall, Mum and Dad, even Neville in his time, unless the wound in the world can be healed before then.
> Harry had checked the books, had learned that since he was too young to have sexual thoughts he would be able to approach a unicorn without fear. The same books had said nothing about unicorns being smart. Harry had already noticed that every intelligent magical species was at least partially humanoid, from merfolk to centaurs to giants, from elves to goblins to veela. All had essentially humanlike emotions, many were known to interbreed with humans. Harry had already reasoned out that magic didn't create new intelligence but just changed the shape of genetically human beings. Unicorns were equinoid, were not even partially humanoid, didn't talk, used no tools, they were almost certainly just magical horses. If it was right to eat a cow to feed yourself for a day, then it had to be right to drink a unicorn's blood in order to stave off death for weeks. You couldn't have it both ways.
> Professor Quirrell breathed in, breathed out. There was quiet for a time in the infirmary, the two of them watched only by the elaborately ornamented stone of the walls.
