Meet the prophets who got it wrong. Like, really wrong.
Prophet: Zorvath (a.k.a. "The Guy Who Forgot to Build a Sturdy Dike")
Year: 10,000 BCE
Disaster: Atlantis sank into the sea because Zorvath thought it'd be a good idea to build the city on top of a giant mud pit. Who needs a floodplain, am I right?
