The ominous book Claire peeked inside of just so happens to hold one of Illian's more darker secrets, and it shows a full-cover drawing of a man leaning on a set of books, grinning mischieviously. He is wearing fancy clothes with a lot of lace, almost keeping you from seeing the two large horns on his forehead and the two demonic-looking wings on either side of him.
The man has long, wavy hair and pointy ears; and you see a flash of a fang in his smile. Two eyes stare at you tauntingly, seductively, captivating.
