Because of their haste, they did not have time to precisely scan the planet Earth, and so they did not locate their enemies hidden deep within the caverns and beneath the seas of pre-diluvian Earth. The masters of the Nephilim were relatively convinced that even if their enemies were on Earth they could not survive the paroxysms and furor that Tiamat’s obliteration would bring on. However, these unknown pursuers did not just leave our solar system without instigating precautionary measures.
Before they made the journey back to their own planet, they established an etheric barrier around our planet that would be along the same orbit trajectory as the Moon’s around the Earth. This barrier still exists and is utterly impenetrable to the Atlantean progeny, because the technology by which it was erected was of an extremely advanced level.
From that time onwards, the Moon would come to represent (in almost all cultures) arcane powers of protection and magic.
This apotropaic barrier, often referred to as by native peoples as the “the great web in the sky,” was put there obviously to prevent the Atlanteans from ever leaving this place.
The Earth was to be their tomb.
Before their discovery of the existence of the “Stargate,” the Nephilim intended to one day vacate this planet that has long been their terrible prison. They did not come here by choice and have not had a good time of it since their forced arrival. They have been as the Bible relates, “chained into the pit.” It is their intention to break their chains and change galactic address as soon as the technology exists to make this possible.
(One would do well to notice how many movies and how much art and corporate designs embody the theme of release from some form of captivity).
The descendants of the Atlanteans were giving themselves a pat on the back during the Renaissance. They were satisfied that they had taken control of the planet economically and were making good progress toward reconstructing the science and technology they once enjoyed.
In fact, as writers such as William Bramley have pointed out, they even had the ability to build craft for flying out of the Earth’s atmosphere. It was at this point, or probably some time before, that they discovered the existence of the “Stargate.”
They then realized to their horror that even if they were able to successfully reproduce all the advanced hardware they required, they probably could not leave the planet anyway. This knowledge caused them intense displeasure and confusion. They may have come across the Stargate by attempting to go beyond it, having at least one of their special crafts destroyed.
Such an event seems to have taken place in Siberia more recently.
In Mankind, Child of the Stars, the authors detail an account of a strange, previously unexplained accident:
When the predicament of the Stargate was fully accepted, the scions of Atlantis knew something had to be done, lest all their aeons of effort and tribulation would be for nothing.
They convinced themselves that what technology could erect, technology could eventually take down. It became their avowed and solemn intention to move humanity forward to the point where it became intellectually evolved and capable enough to develop the high technical sciences that could expedite their freedom.
So, it was decided by the Royals of England, the Tudor Dynasty, that though their present researches and operations would not be halted, a new approach was needed.
The man with the idea for this new approach and the one who would undertake its execution was Sir John Dee, the court astrologer and ambassador of Queen Elizabeth Tudor.
