It basically covers the perspective of history from Thoth's point of view. During a magnetic pole shift we enter an electromagnetic null zone which erases our physical memories and we have to start all over. In one of the books I read immortality is described as not losing your memory and having to start over. There's a way to protect against this by using the Merkaba mediation where a three-dimensional tetrahedron/Star of David is placed around the body. Thoth and his masters had there's operating and didn't lose their memories. Thoth claims to have been through five magnetic shifts.
The humans on this planet have been apart of an experiment to achieve Christ consciousness within 13,000 years rather than the hundreds of thousands of years it normally takes. This has never been done anywhere in the universe before. A majority of the ancient temples on the planet were placed on grid points to accelerate this goal. Apparently Thoth accomplished the objected and ascended. More information is in The Emerald Tablets of Thoth: The Atlantean & The Ancient Secret of the Flower of Life Vol. 1&2 by Drunvalo Melchizedek who was one of Thoth's students.
