"The spirit who said "For we are many," in ancient scriptures. The name comes from the Roman military term for an army of 3,000 to 6,000 men."
Legion is a group of demons based on the story mentioned in Christian literature. In the account, Jesus was said to have healed a man from a region in Caesaria Maritima in the Near East who was possessed by many demons. Jesus casts the demons out of the man, granting their request, and allows them to dwell in a herd of pigs. The pigs then drowned themselves in the Sea of Galilee.
"An evil spirit whose name is derived from the Roman military term. Legion appears in Chapter 5, the Gospel of St. Mark, possessing a human body and uttering the line: "My name am Legion, for we are many." As its name signifies, it is not a single entity, but a vast amalgamation of souls. These souls, driven by hatred and jealousy, have lost all sense of individuality. In classical Latin, Legion's name was "Legio," the term for a Roman military unit of 5,000 soldiers. From this, the name "Legion" came to mean "army.""
