The great beasts that inhabited Europe, Asia and North America die off as a result of mutations and diseases caused by the solar flare. All relics of the Atlan-tean civilization are destroyed. The people who were Gruad's erstwhile countrymen are either killed or driven forth to wander the earth. Besides Gruad's Himalayan colony there is one other remnant of the High Atlantean era: the Pyramid of the Eye, whose ceramic substance resisted solar flare, earthquake, tidal wave and submersion in the depths of the ocean. Gruad explains that it is right that the eye should remain. It is the eye of God, the One, the scientific-technical eye of ordered knowledge that looks down on the universe and by perceiving it causes it to be. If an event is not witnessed, it does not happen; therefore, for the universe to happen there must be a Witness.
Among the primitive hunters and gatherers a mutation has appeared that seems to be spreading rapidly. More and more people are being born without fur and with hair in the same pattern as Gruad's. The Hour of God's Eye has caused mutations in every species.
From the Himalayas the rocket ships of the Unbroken Circle, painted red and white, swoop out in squadrons. They sweep across Europe and land on the brown islands where Atlantis used to be. There they land and raid a city of refugees from the Atlantean disaster. They kill many of the leaders and intellectuals and herd the rest aboard the ships, fly to the Americas and deposit the helpless people on a vast plain. Far below their route of passage lies the Pyramid of the Eye at the bottom of the Atlantic. The base of the pyramid is covered with silt and the break where the upper part of the pyramid had floated on antigravity projectors is also covered. Still the pyramid itself towers over the mud around it, taller by three times than the Great Pyramid of Egypt, the building of which lies twenty-seven thousand years in the future. A vast shadow descends upon the pyramid. There is a suggestion in the darkness of the ocean bottom of giant tentacles, of sucker disks wide as the rims of volcanos, of an eye as big as the sun looking at the eye on the pyramid. Something touches the pyramid, and enormous as it is, it moves slightly. Then the presence is gone.
The pentagonal trap in which the people of Atlantis had heroically and brilliantly caught the dread ancient being Yog Sothoth has been, amazingly, undamaged by the catastrophe. Being on the southern plain, which was relatively uninhabited, the Pentagon of Yog Sothoth becomes the center of a migration of people who survived the disaster. Emergency cities are set up, those dying of radiation sickness are treated. A second Atlantis begins to take root. And then, from the Himalayas, the ships of the Unbroken Circle come swooping down on one of their raids. Lines of Atlantean men and women are marched to the walls of the Pentagon and there mowed down by laser fire. Then explosive charges are placed amid the heaps of bodies and the masked, uniformed men of the Unbroken Circle withdraw. There is a series of explosions; horrid yellow smoke goes coiling up. The gray stone walls crumble. There is a moment of stillness, balance, tension. Then the piled-up boulders of one side of the wall fly apart as if thrust by the hand of a giant. An enormous claw print appears in the soft soil around the ruins of the Pentagon. The masked men of the Unbroken Circle race frantically for their ships and take off. The ships dart into the sky, stop suddenly, waver and plummet like stones to explosive crashes on the earth. The surviving refugees scream and scatter. Like a scythe going through wheat, death sweeps among them in great arcs as they run in massed mobs. Mouths open in soundless screams, they fall. Only a handful escapes. Over the scene a colossal reddish figure of indeterminate shape and number of limbs stands triumphant.
In the Himalayas, Gruad and the Unbroken Circle watch the destruction of the Pentagon and the massacre of the Atlanteans. The Unbroken Circle cheers, but Gruad strangely weeps. "You think I hate walls?" he says. "I love walls. I love any kind of wall. Anything that separates. Walls protect good people. Walls lock away the evil. There must always be walls and the love of walls, and in the destruction of the great Pentagon that held Yog Sothoth I read the destruction of all that I stand for. Therefore I am stricken with regret."
