There's not many creeps in video games that are bonafide scary. One such character is the "legion", AKA Granfaloon, that screaming mass of humanity out to attack various vampire slayers in assorted Castlevania games. While today's connotation of "legion" makes us think of a military group, Legion was originally a demon from the Bible that possessed men and was "composed of many". So, essentially, it's the same thing as the ill-will goo from Ghostbusters 2. To jump thoughts, it's a shame that the Christian Old Testament was derived more from the more stoic Torah and not the Talmud. The Torah, in essence, was a lot of legal mumbo jumbo, laws, housing codes, mixed in with some tales of moral value. The Talmud reads more like a storybook, with twists and turns, characters that exist merely to personify the vagary of life, and so on. Lesbians everywhere cling to the tale of the mythic Lilith, the gal from the Garden who didn't want to answer to 'no man (or, for that matter, no God).
Back to the Bibilical Legion. Legion was essentially one man who got possessed by multiple demons, and if we read the New Testament as literature and not scripture, a clever metaphor for Roman interference. In a rather humanistic touch, the demons possessing said man plead with Jesus to free them from their unholy obligation, IE a return visit to the depths of Hell. Jesus extracts the spirits and puts them into a herd of nearby pigs (as if you couldn't tell, the Jews of old really had something against poor pigs). The swine herd then drowned themselves in the Sea of Galilee, assumedly freeing the demons and of course, purging Legion.
The moral of the story: you CAN learn stuff from video games! And the other moral is my lunch break is over, so back to work!
