The Kingdom of Shadows was that vibrational octave into which were brought those who had come up from a lower cosmic cycle when the gate was opened by man. This was in the third or Polarian cycle, and those who delved into the darkness were men who loved material power rather than devote their lives to spiritual things. The entities they brought forth were formless as only consciousness was brought up and then bodies had to be formed on that plane.

Separated from their cosmic consciousness and its creative power - like the elementals - they could not connect with this cycle because they had not developed their primordial arcs. Only through the will of man and the withdrawal of life force from blood could they take form.

The masters drove most of them back through the lower gate, but there were some who remained in the place that had been built for them. They came out only when their name was called and a blood sacrifice was offered. They took the appearance of man, but their real appearance was the body of a man or woman with a serpent's head.
They could erect a mesmerizing glow around themselves, giving the appearance of looking human.

This is the reason for the belief in the hypnotic power of the snake.

They took on the forms of leaders who had been secretly killed, and gradually they and the people who had created them took control of the nations. They really looked quite like humans, but there was one word they could not utter.

This was taught to men by the masters, and it became the law that every man who held an office should be had to speak this word before the people once per lunar month. If he could not, he was killed. Thus they were driven from their places among the people and slowly forgotten, however, some still exist in their own place without being able to enter our world, because the people have forgotten the rites with which one can call them. The word was: KININIGEN.
