Who did Aslan say was responsible for bringing the Witch into Narnia? *

The Son of Man (Digory) brought the evil witch to Narnia.

"Son of Adam," said the Lion. "There is an evil Witch abroad in my new land of Narnia. Tell these good Beasts how she came here." A dozen different things that he might say flashed through Digory's mind, but he had the sense to say nothing except the exact truth. "I brought her, Aslan," he answered in a low voice. "For what purpose?" "I wanted to get her out of my own world back into her own. I thought I was taking her back to her own place."
