Some fled to the hollow earth, and some assimilated into the existing cultures, being worshipped as gods due to their Vril powers. Their advanced technology caused some type of cataclysm which produced the great flood and submerged their continent. Vril could be Ancient Aliens that seeded our planet from their Island Continent of Atlantis who became corrupt and decadent and began messing with the natural order through genetic experiments and their limitless Vril technology. There's enough evidence to go either way with this one. Sorry for any mistakes and or spelling errors I am doing this on my phone. I am not denying the technological superiority of the Vril People, I am just saying the reason they got to this point was from a little help, if you catch my drift. They are going into the core of the earth, retreating from the surface and light (I know the Earth's core does have lava, but maybe not for the Hollow Earth. What person could escape a cataclysmic event brought on by a diety without the aid of another diety? To retreat within the earth's core is like a metaphor for evil. Their power has to come from a different and darker source. If Noah's Flood was meant to wipe out the evils of this world and the Vril People managed to escape it without being on Noah's guest list I presume they are not in favour with God. Personally, I think it is the Biblical People because it would connect to the Demonic Presence within zombies. But, I have heard people refer to them as extraterrestrial beings. Now, I know that The Coming Race says the Vril-Ya are humans who, escaped Noah's flood. The one question that plagues me is whether or not the Vril People are "Alien-aliens" or aliens in the sense of something being foreign.
