The Ones You Love

 The people that are dearest to Claudia, Pete and Myka are in danger from artifacts sent to them by Brother Adrian. While they rescue their family, Steve and Mrs. Frederic go to the Vatican. They discover that the brotherhood has a dark secret. They also discover the Brother Adrian attacking the Warehouse is a figment of Artie`s imagination and that he is having a psychotic break. The nature of the evil that Artie has created is revealed as himself—the astrolabe has caused Artie to suffer a mental breakdown that has caused him to hallucinate a malevolent apparition of Brother Adrian that "steals" artifacts and unleashes them on his loved ones. In reality it has been Artie that has been stealing the artifacts and unleashing them while in his Brother Adrian "persona". Leena is killed while trying to help him.
