If Penny didn't believe in magic, she sure did now when the blood that fell down started to move on the very lines that were drawn on the parchment before the ritual had started. It was as if the blood had suddenly taken life which started to move gradually from the center to all the endpoints, curving to meet each other until the entire parchment looked to be designed in just ink.
