The Perversion of Atlantis

A comet broke up in outer space and smashed into the ice sheet, it created literally oceans worth of water. This is where we get into things like black rain and stuff like that. The reason why I think this happened is because Atlantis was almost like at the end of the a golden age of sorts. It was when all this different knowledge began to become perverted. So heavily that it ended up creating a low-prequence of it. Sure, it's not anybody's own.
