If I remember them correctly, the Emerald Tablets comments on the fact that Thoth seen the rotations of the polar points/magnetism change throughout the worlds life cycles.

I think it is a normal phenomena and has drastic changes on the environment. If they do shift, which they are, this would mean the equator/heat map of the world would change.

The pyramids in Antarctica makes sense, as it probably was once hospitable in the past.

The codes and manuals and speech recognition for the temporal stargates were used to bring these entities across and there were quite a few portable stargates that could stay open for a few minutes . To those not in the know this was considered magic. To this day some of these ancient codes have survived and are still in use by some magic groups to attempt to bring entities over from the other side. Although in most cases people lack the right tools to fully do so. Usually what happens is that you get attention from the ones already here. For some reason Deamons have a hard time moving in circles and prefer right angles. So circles are used to protect the magician. And right angles are used outside the circle to coerce them. The emrald tablets of Thoth gain great wisdom into many of these workings but the words MUST NOT be read aloud. Reading those ancient passages aloud is a sure fire way to attract attention. Deamon memory spans many lifetimes and they remember those words uttered like they were yesterday.

Eventually In some ancient time there was a pact made between Deamons and humans. Some " rules to the game". The pact was called " the covenant of salt" To this day salt is one of the only things that will ward off Deamons.. Yeshuah knew this and this is why he modeled the system of baptism off of full body submersion into SALT WATER. Salt water will temporarily knock the astral snakes off of your body and provide a clean start to accruing polarity again. Ask any deamon hunter living , they will tell you salt works on just about every deamon. Holy water is just salt water that is blessed in most cases.

Other magic is actually old source code from the matrix and with the right tools can manipulate certain things. This is rarely done successfully anymore as this source code was a collection of complied script systems that sped up thought and made it manifest more quickly.

Strange enough, The Atlanteans discovered that life on this planet was actually due to some parts of the incarnation trap system dispersing energy gained from program polarity and keeping the system perpetually locked and fueled. So while its motives seemed malevolent it did provide life energy to sustain the planet. A balance of dark and light so to speak appeared necessary to keep life from fleeting one way or another.
