According to Edgar Cayce, Atlantis fell in stages after its people misused powers they no longer had the wisdom to control. In trance, he described a civilization divided between the Law of One and the Sons of Belial, with crystal energy, aerial craft, altered human forms, hidden archives, mass migration, and a final catastrophe that scattered survivors across Egypt, Central America, Iberia, and beyond. The Forbidden History of Edgar Cayce's Atlantis reconstructs that account directly from the numbered readings, separating Cayce's own words from the mythology later built around them. It investigates Poseidia, Bimini, the Sphinx, the Hall of Records, disputed prophecies, reincarnated Atlantean souls, and the archaeological and geological evidence used both to support and challenge the case.
