London, 2038. According to legend, when the ravens depart the Tower of London, it will crumble to rubble and disaster will befall England. As man became more dependent on science, believing only in what he could define or create, ancient knowledge and rituals were lost to the antiquity of time. Prophecies that had stood as warning for untold generations were seen as archaic folly or ignorant superstition. So, when the harbingers of evil began to manifest, few saw and fewer believed. When the demons finally came, there was little that stood in their way.
