“Dumbledore was on his feet again, pale as any of the surrounding Inferi, but taller than any too, the fire dancing in his eyes; his wand was raised like a torch and from its tip emanated the flames, like a vast lasso, encircling them all with warmth.”

“Directly above them, framed in the doorway from the Brain Room, stood Albus Dumbledore, his wand aloft, his face white and furious. Harry felt a kind of electric charge surge through every particle of his body - they were saved.”

“At that moment, Harry fully understood for the first time why people said Dumbledore was the only wizard Voldemort had ever feared. The look upon Dumbledore's face as he stared down at the unconscious form of Mad-Eye moody was more terrible than Harry could have ever imagined. There was no benign smile upon Dumbledore's face, no twinkle in the eyes behind the spectacles. There was cold fury in every line of the ancient face; a sense of power radiated from Dumbledore as though he were giving off burning heat.”
