After Anael had made sure that Alcuin had everything he needed, he set off to do as he had promised him, and reached Kersen's home right as the sun was setting behind the London buildings. He landed in a nearby, small street, then shed the wings and reappeared to the world, to walk on over to Kersen's door. He rang the bell, then said quietly to the door, hoping that Kersen might be listening, and would hear him, "It's Anael."
