Trackers like Malfoy became a necessary part of the regime. The Dark Lord needed people who could fade into the background, who could find that which had been hidden. Spies were usually uncovered. How they seemed to always be found was still a mystery. Rumors existed that they had one amongst them that could read the essence of a person's very soul with only a quick glance. It was an archaic form of magic that hadn't been used in centuries. Whoever this mystery sort-of Seer was had never been discovered. When a broken and battered people searched for a savior, it wasn't unusual for them to make legends from fantasy.
