She was fascinated by the idea if terrified at the same time. Old magicks had to be used. It was incredibly dangerous to tap into power that was so ancient and dark. Once she stumbled on a book that had been confiscated in a raid by the Ministry of one of the Dark Lord's suspected enemies. Truthfully, it was just a doddering old fool who had an impressive collection of texts and artifacts that didn't appreciate the Ministry of Magic sticking its nose into his private affairs. The old man had been thrown in a cell to await a trial that never happened. He'd died of an apparent heart attack only days later. Many of the old ones died before their trials. Hermione had the chance to look at some of the evidence that had been gathered. One of the books was darker than anything she'd ever read. If she'd flipped through it and found out how to make a horcrux, she wouldn't have been surprised. The few descriptions she read about the process of bringing the dead back to life filled her with dread and haunted her dreams for months.
