In the video game Shadow of the Colossus (created by sony in 2005) the main character "wanderer" takes his lover to a distant land and asks a demon to help revive his lover. The demon says that he will help you if you can kill all sixteen colossi in the land. The wanderer has a magical sword that can kill the colossi by stabbing and revealing their weak points. So this raises my question Where Did the colossi come from?
(Note: the demon has part of him sealed in each colossi so when you kill one part of him possesses you (wanderer))
