The alarm, which had indeed been built to warn Lud's long-dead residents of an impending air attack (and which had not even been tested in almost a thousand years), blanketed the city with sound. All the lights which still operated came on and began to pulse in sync. Pubes above the streets and Grays below them were alike convinced that the end they had always feared was finally upon them. The Grays suspected some cataclysmic mechanical breakdown was occurring. The Pubes, who had always believed that the ghosts lurking in the machines below the city would some day rise up to take their long-delayed vengeance on the still living, were probably closer to the actual truth of what was happening.
Certainly there had been an intelligence left in the ancient computers below the city, a single living organism which had long ago ceased to exist sanely under conditions that, within its merciless dipolar circuits, could only be absolute reality. It had held its increasingly alien logic within its banks of memory for eight hundred years and might have held them so for eight hundred more, if not for the arrival of Roland and his friends; yet this mens non corpus had brooded and grown ever more insane with each passing year; even in its increasing periods of sleep it could be said to dream, and these dreams grew steadily more abnormal as the world moved on.
