From The Grey House:
They were back at Vincent’s estate before long. Everyone was left to their own devices. Rebecca, wanting to stretch her muscles, turned into a wolf and ran off. Vincent owned the hill the house was on and the one next to it. The two hills were filled by many farms run by humans. They willingly gave their blood to Vincent and the other seven vampires who lived under Vincent’s protection. The werewolves could run the land as wolves but were warned on a regular basis that the humans had tranquillizer guns to take them down if they did something foolish. If for some reason the tranqs didn’t take them down, the humans had shotguns with silver buckshot, and would use them if they were threatened.
