From The Grey House:
The creatures that only appeared human, were now standing taller than Vincent. At over nine feet tall, they had to hunch in order not to hit their heads on the ceiling. Their clothing ripped, revealing hairy but matted arms and legs. Their most impressive features were their fangs and foot-long claws. Vincent had made a deal with the werewolves of the area. Work for him and he would house them and help to feed their more dangerous appetites. Vincent felt it was better to work with the supernatural population rather than hunt them down. Wars killed humans, which he needed, and brought Slayers, which he didn’t need.
