It was dark, for she always moved in the night. During the day the city was nothing but crowds, filth, and voices shouting in a blurring mass of confusion. But when the world was lit only by the moon all was quiet. She ran silently across the rooftops, a black cloak flying through the air behind her, a hood shielding her face. The wind rushed past as she seemed almost to fly through the air. Then she stopped, crouched on the cold stone and listening as two people walked down the streets towards their home. She didn't care what they were talking about, only that she could hear them and they didn't know. A grin spread across her face and she started running again.
