On the way to the mountain, Lockhart’s driver told him about the strange incidents and extraordinary history of this nursing home: According to legend, it was a baron’s castle more than two hundred years ago, and the baron has been doing it on the villagers. Human experiments were conducted to cure the infertility of his wife (and sister), so as to maintain the purity of the next generation's blood. In the end, his experiment was successful, but the villagers discovered his secret and burned the castle in anger.
