The destruction of Old Earth and the reduction of the human population to eight had done for the idea that there was a God, at least in any sense remotely similar to how most pre-Zero believers had conceived of Him. Thousands of years had passed before anyone, even in the most remote outposts of human settlement, had dared to suggest that religion, in anything like its traditional sense, might be or ought to be revived. In its place a new set of thoughtways had grown up under the general heading of "dukh," a Russian word referring to the human spirit. Dukh-based institutions had developed under the general term of "kupol," a word that harked back to the glass bubble that had served as a kind of interfaith chapel and meditation room on Endurance . Modern-day kupols all traced their origins back to that structure, which Dubois Harris had called the Woo-Woo Pod. When people nowadays watched scenes from the Epic that took place in it, they were in the backs of their minds thinking of their local kupols and the people who staffed them. A professional member of a kupol’s staff was generally called a dukho, a truncation of the Russian word "dukhobor," meaning one who wrestled with spiritual matters. Kupols, like churches of old, were supported by contributions from their members. Some, as on the Great Chain, were richly endowed, magnificent buildings. Others, like the one in the Q, were just quiet rooms where people could go to think or to seek help from what amounted to social workers. Dukhos tended to trace their lineage back to Luisa, who had played a similar role during the Epic, and some of the better-educated ones drew explicit connections between their kupols and the Ethical Culture Society, where Luisa had gone to school in New York. But Luisa, of course, had not produced a race. The dukho profession had ended up being dominated by Julians. The Julian habitat of Astrakhan, which hovered anomalously in the middle of the Dinan segment, had become a sort of hothouse for the production of dukhos of various denominations. Kath Two was able to establish that Ariane had originated from there, but little else. It was fine. There were ample reasons for Ariane to keep to herself and lead a quiet life.
