A roaring, billowing noise behind him gave him a moment’s warning. He turned and saw both Ron and Crabbe running as hard as they could up the aisle toward them.
“Like it hot, scum?” roared Crabbe as he ran.
But he seemed to have no control over what he had done. Flames of abnormal size were pursuing them, licking up the sides of the junk bulwarks, which were crumbling to soot at their touch.
“Aguamenti!” Harry bawled, but the jet of water that soared from the tip of his wand evaporated in the air.
“RUN!”
Malfoy grabbed the Stunned Goyle and dragged him along; Crabbe outstripped all of them, now looking terrified; Harry, Ron, and Hermione pelted along in his wake, and the fire pursued them. It was not normal fire; Crabbe had used a curse of which Harry had no knowledge. As they turned a corner the flames chased them as though they were alive, sentient, intent upon killing them. Now the fire was mutating, forming a gigantic pack of fiery beasts: Flaming serpents, chimaeras, and dragons rose and fell and rose again, and the detritus of centuries on which they were feeding was thrown up into the air into their fanged mouths, tossed high on clawed feet, before being consumed by the inferno.
Malfoy, Crabbe, and Goyle had vanished from view: Harry, Ron and Hermione stopped dead; the fiery monsters were circling them, drawing closer and closer, claws and horns and tails lashed, and the heat was solid as a wall around them.
“What can we do?” Hermione screamed over the deafening roars of the fire. “What can we do?”
“Here!”
Harry seized a pair of heavy-looking broomsticks from the nearest pile of junk and threw one to Ron, who pulled Hermione onto it behind him. Harry swung his leg over the second broom and, with hard kicks to the ground, they soared up in the air, missing by feet the horned beak of a flaming raptor that snapped its jaws at them. The smoke and heat were becoming overwhelming: Below them the cursed fire was consuming the contraband of generations of hunted students, the guilty outcomes of a thousand banned experiments, the secrets of the countless souls who had sought refuge in the room. Harry could not see a trace of Malfoy, Crabbe, or Goyle anywhere. He swooped as low as he dare over the marauding monsters of flame to try to find them, but there was nothing but fire: What a terrible way to die… He had never wanted this…
“Harry, let’s get out, let’s get out!” bellowed Ron, though it was impossible to see where the door was through the black smoke.
