... When the original pursuers of the “Serpent Brotherhood” destroyed the planet Tiamat, they made ready to leave this solar system and return to their own. They had to leave in a hurry, so as not to be hindered by the cosmic forces which would be unleashed throughout the solar system. 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 onward, the Moon would come to represent (in almost all cultures) arcane powers of protection and magic. This apoptotic 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.

The higher angelic intelligence's which rule our solar system may have erected the cosmic barrier after relative normalcy had returned to the planetary grid. The facts are not clear as to how it got there or what agency is really responsible. C. S. Lewis refers to this barrier and the quarantine of the “Bent Ones” in his writings, terming the Earth tomb of the aliens, Thulcandra (the “Silent Planet”).

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).
