Deeper magic from before the dawn of time

"Oh, it's too bad," sobbed Lucy; "they might have left the body alone."

"Who's done it?" cried Susan. "What does it mean? Is it more magic?"

"Yes!" said a great voice behind their backs. "It is more magic."  They looked around.  There, shining in the sunrise, larger than they had seen him before, shaking his mane (for it had apparently grown again), stood Aslan himself.

"Oh, Aslan!" cried both the children, staring up at him, almost as much frightened as they were glad.

"Aren't you dead then, dear Aslan?" said Lucy.

"Not now," said Aslan.
