I think I have found the original location of this Demonseed article. I’m still not done with it of course, but it’s sure opening a lot of interesting side chases.

Apparently, this author has a whole Earthlink site dedicated to “Subterranean Myths & Mysteries“. From that site:

This website is dedicated to the idea that the structure of our planet, the history of our species, the underlying truths disguised as our myths, legends, folklore and “pop culture” imagery, are not quite what we have been led to believe.

The Earth itself is much more stratified and complex in structure than one might realize, and our species has perhaps experienced, through the ages, encounters and conflicts with “others,” non-human intelligences or beings of various types who have seldom, if ever, been our friends. Memories and accounts of these encounters have come down to us in the form of folklore and mythology, often viewed with superstitious terror or awe through the conditioned lenses of religions, or religious interpretation.

There are also something like 10 other articles by this guy about this stuff. Hot dog! What a find! Man, this guy’s website sucks though, maybe I’ll do him up one as a favor.
