The Darkness

The Darkness is the total absence of light on Kalgash, a concept so alien and terrifying to a civilization that has never experienced night that it functions as both a literal astronomical event and a profound psychological and existential threat. Its decisive significance lies in its power to shatter the human mind, triggering mass insanity, societal collapse, and the cyclical destruction of civilization, as predicted by the Apostles of Flame and confirmed by the scientists' discovery of the eclipse of Dovim.

Definition and Cultural Context

On Kalgash, where at least two suns are always in the sky, Darkness is not a natural phenomenon but an abstract, almost obscene concept. The word itself is rarely used in polite company, and the less educated find it threatening to even let their minds dwell on the possibility that the six suns might disappear. This cultural taboo is so deep that everyone sleeps with a godlight, a small lamp that provides a constant, comforting glow. The psychologist Sheerin 501 explains that mankind has an instinctive fear of the absence of light, a condition he terms "claustrophobia," because the lack of light is always tied up with enclosed places. The very idea of a world with only one sun, which would experience daily periods of darkness, is met with involuntary horror by the astronomer Beenay 25, illustrating the profound psychological conditioning of a people who have evolved under perpetual sunlight.

Psychological Impact and the Tunnel of Mystery

The catastrophic psychological effect of Darkness is demonstrated by the Tunnel of Mystery, a ride at the Jonglor Centennial Exposition that plunges passengers into total darkness for fifteen minutes. The ride causes widespread trauma: some die of fright, others emerge permanently deranged, and even the strongest psyches are severely battered. Sheerin, who rides the Tunnel himself, experiences a terrifying ordeal, feeling sweat break out, his knees shake, and his forehead throb as he peers into an utter void. He throws away his abort switch in a moment of panic and is left trembling, realizing that no force in the world could get him to take a second trip. The victims, like the longshoreman Harrim 682, develop severe claustrophobia, refusing to go indoors, and later swing to claustrophilia, becoming afraid to go outside. Sheerin concludes that Darkness is more than most can handle and that the Tunnel is deadly, a conclusion that leads to its permanent closure.

The Eclipse and Universal Madness

The Darkness that arrives with the eclipse of Dovim is not a brief ride but a planetary event lasting hours. Sheerin predicts that the effect will be universal madness, with people affected to varying degrees, from short-range disorientation to complete and permanent destruction of the reasoning powers. He argues that no one will be entirely unscathed. The prediction is borne out when the eclipse begins: the city of Saro City descends into immediate hysteria, with rioters, looters, and panicky mobs. The Darkness itself is described as a palpable entity, a thick blanket that smothers the world. The astronomer Athor 77, watching the last light of Onos fade, knows he will never see it again as a sane man. The coming of the Darkness is the trigger for the complete breakdown of civilization, as people, driven mad by the absence of light, desperately seek to create it by any means, leading to the fires that consume the cities.

The Darkness as a Cyclical Force

The Darkness is not a singular event but a recurring catastrophe. The archaeologist Siferra 89's excavation of the Hill of Thombo reveals a series of settlements, each destroyed by fire at intervals of approximately two thousand years. The correlation between these fires and the astronomical eclipse of Dovim, which occurs every two thousand and forty-nine years, confirms that the Darkness is a cyclical force that has repeatedly brought about the end of civilization. The Apostles of Flame, through their Book of Revelations, have preserved the memory of these cycles, describing the "Cave of Darkness" that swallows the suns and the subsequent madness and fire. The scientist Athor, after confirming the existence of the invisible satellite Kalgash Two that causes the eclipse, realizes that the model of the solar system he knew was erroneous and that a great strangeness exists in the midst of the known universe. The Darkness is thus revealed as an impersonal, astronomical inevitability, a force of nature that periodically resets the course of human history.
