The Holy Oak Asylum was a reputable institution during the early 1900s. However, over time, it deteriorated and became one of the world's most poorly managed mental hospitals. It was under the control of the Holy Oak Church, which was opposite the Asylum. In 1980, both the Asylum and the Church ceased their operations.
Despite being closed and abandoned, a group of amateur ghost hunters discovered that the Asylum was not empty. While exploring its halls, they encountered a young girl dressed in a hospital gown. It was later revealed that Lily had been wandering the empty halls of the Holy Oaks Asylum for over six decades.
