Astra gave a sigh -she wasn't sure if it was relief or disappointment- as the dog took it's leave.  If it had attacked her job would be so much simpler, kill it and move on, but now she was utterly confused as to her next move.<i>How do dogs grow that big naturally?  I know it's no creature of the night as a were of some sort wouldn't have turned down prey like that...</i>Still thinking, Astra rose to her full height of 5'8", her slim body seeming to unfold as she brought herself up to a standing position.  Her brown leather jacket, long ponytail of black hair, and loose jeans caught the wind that blew across her chosen vantage point as she made her way to the rooftop access and hurried down the stairs to the street level.  If the dog was unnatural then the strangers it had seemed ready to attack might know something about it.
