As Michael delved deeper into the mystery of the building, he discovered an old manuscript in the archives that had been written by a former employee who had vanished without a trace. The manuscript detailed strange occurrences and unexplainable events that had taken place in the building years earlier.
Michael's research led him to believe that the manuscript's author had been driven to madness by the same sinister force that was plaguing him. As he dug deeper, he realized that the building was a hotbed of supernatural activity and that he was in grave danger.
