In the end, it was decided that all of them were going to take a different room of their own as money was no problem. The only problem that could be was that they had just killed two Vampires, and quite a few people knew about them, but even that wasn't a major problem since there were only two Vampires in the city.
Before killing Wang, Atlas had forced him to give some answers. By the end, Wang was so horrified that he blabbered like a parrot, telling Atlas everything about exactly how many of them there were. In the end, he even told Atlas why they came to this city and what their goals were.
It was through Wang that Atlas came to know about the crack in the Blood Council. He just found out that even in the Blood Council, not everyone was on good terms and that one of the Blood Council Members had betrayed the rest.
That was why so many vampires had gone to different cities, looking for the woman.
