If you haven't seen the movie, you should give it a viewing. It's several years old, so it shouldn't be too hard to get your hands on. I was just watching this part today and it still gives me chills.
"...the Witch knew the Deep Magic, there is a magic deeper still which she did not know. Her knowledge goes back only to the dawn of time. But if she could have looked further back, into the stillness and darkness before Time dawned, she would have read there a different incantation. She would have known that when a willing victim who had committed no treachery was killed in a traitor's stead, the Table would crack and Death itself would start working backwards" (C.S. Lewis, The Lion, The Witch and the Wardrobe, 1950).
