THE ANCIENT ENEMY THAT DWELLS BENETH THE WORLD

My great grandfather tried to teach my mother and her siblings the old ways of the Apache. One time, he told her of a secret war that lasted for countless generations. This war is against a race of underground dwellers that surfaces roughly every 40 yrs. It took shamans with powerful medicine and skin walkers' might to drive them away. These underground invaders are extremely hard to kill. The only description that she could translate was they are white skin (pale), have sharp claws and come out of the ground very hungry. The creatures send scouts up to see if it is safe to feed on humans and anything else they could find. If the scouts did not returned, they wouldn't send the larger group up to feed. But if the scouts returned that met that man has forgotten them.
My great grandfather fought them before. He was getting ready fight them again when he was telling her the story. He was over eighty at the time and told her that there are few left who knows the ancient enemy cycles. He said that one of their exit points is near Post, Texas. Where the ground is red. Does he mean red sediments? He said there are signs of there presence in the areas they hunt. You got to have the knowledge to recognize them. Later that day, a group of other natives Americans came to the house and he went with them. Weeks later, he came back and told her that they were successful. He worried “Who will help the next generation be ready for the arrival of the Ancient Enemy?” That was over forty years ago.
The movies Burrowers and The Descent reminded me of this story a little bit. I wonder how many other tribes in the world has this enemy in there legends. I have also heard similar description from military sources. I was telling this to my friend. Then he told me a story as well. His is ex-military and was recruited by a 33 degree Freemason to be in the military. When in the service, he made many connections. He met one of the crew that made the tunnels for the military. They used the nuclear tunnelers that turned the earth into glass. When making the glass tunnels, they would hit caves. There was enough molten glass to cover the cave openings. In some cases it saved their asses. The creatures would rush the thick glass windows. It was thick enough to hold them back. So, if you one of maintenance crews who takes care of the tunnels. One can see the creatures stare at you through the thick glass like in a zoo. This means that all their underground bases are under threat of being overrun by these pale creatures.
