Far away, near the border of the land of Bonelake as well as Wovile, in midst of the forest, a castle stood hidden which belonged to the vampire named, Hendrick. He stood in the laboratory, looking at his servant who was a witcher who was working on the seat belts with ten switchers who had been strapped to the seats of the chair.
The switchers were the creatures from the dark, from the realm of the dead whose only ability was to take forms of the people who were either dead or were alive with the only criteria that they had to touch the person they were taking the form of.
Apart from mimicking and taking the shape of a person, they had no other ability. These switchers were the same people who used to work for the black witches and had been deceived by coming here to only be used as a sacrifice in a few minutes.
