And then, Mog-ur used the power of his great brain.

All those primitive people, with almost no frontal lobes, and speech limited by undeveloped vocal organs, but with huge brains-larger than any race of man then living or future generations yet unborn-were unique. They were the culmination of a branch of mankind whose brain was developed in the back of their heads, in the occipital and the parietal regions that control vision and bodily sensation and store memory.

And their memory made them extraordinary. In them, the unconscious knowledge of ancestral behavior called instinct had evolved. Stored in the back of their large brains were not just their own memories, but the memories of their forebears. They could recall knowledge learned by their ancestors and, under special circumstances, they could go a step beyond. They could recall their racial memory, their own evolution. And when they reached back far enough, they could merge that memory that was identical for all and join their minds, telepathically.

But only in the tremendous brain of the scarred, malformed cripple was the gift fully developed. Creb, gentle shy Creb, whose massive brain caused his deformity, had, as Mog-ur, learned to use the power of that brain to fuse the separate entities seated around him into one mind, and direct it. He could take them to any part of their racial heritage, to become in their minds any of their progenitors. He was The Mog-ur. His was a true power, not limited to tricks of lighting or drug-induced euphoria. That only set the stage and enabled them to accept his direction.
