They, like the Elementals, being separated from their own cosmic consciousness and its creative powers, are not able to combine with this cycle because they had not developed its primal curves. Only by the will of man and the extracting of spirit from blood could they take form.
The masters drove most of them back through the lower gateway but there were some who remained in the place built for them, coming forth only when the name was called and the blood sacrifice was offered. They took on the apparent form of man, but their actual appearance was the body of man or woman with a serpent head.
They were able to cast a hypnotic glamour around them and appear to assume the features of men. It is this which forms the basis for the belief in the hypnotic powers of the serpent. They assume the forms of leaders who were secretly slain and gradually they and the men who called them took over the control of the nations. They had all of the appearance of men, but there was one word they were unable to pronounce. This was taught by the masters to man and it became law that every man who had office must pronounce this word before the people, once each lunar month. If he failed he was killed. This forced them from place among men and gradually they were forgotten, but some still exist in their own place, unable to enter because man has forgotten the rites which summon them. The word was - KININIGEN.
