An army of Weeping Angels had wiped out the Aplan race on Alfava Metraxis in the mid-47th century, but in doing so had remained without a food source to feed on. They were trapped and weakened. Knowing of the fate of its brethren, a Weeping Angel lay patiently waiting in the ruins of Razbahan and feigned being in a "dormant" cycle. Just as it planned, it passed from one private hand to another until it came in possession of a temporal core to help revive its fellow Angels. The opportunity came when it came to be stored in the Byzantium.
