My copy of Vathek by William Beckford. The character Carathis fascinated me from the very beginning. She is a dark sorceress and mother of the main character Vathek. She is simply pure evil. She has no remorse, no sympathy, no conscience. Every scene with her has her contemplating and more often than not, acting out atrocious deeds to aid her magick. She will literally stop at nothing to get what she wants and if it involves infant sacrifice or the mass murders of youths, she'll do it.
