271-91, TB. Jones, Past Horizons: The Discovery of the Imperial Library on Rakis, Arrakis Studies 1 (Grumman: United Worlds) JACUROTa A legendary sietEfa, declared tabu by Fremen generations before the initiation of the Kynesian ecological transformation. Jacurutu had, by the time of the Aliate Imperial Regency, long since become a myth-its actual historical existence doubted and its name invoked as a fearful object lesson in the discipline of water-ccnservau'oa that pervaded Fremen society. Sietch Jacurutu was originally inhabited by a tribe known as the fduali, "water insects." It was so known because its members would not hesitate to steal another Ftemen's water- the most heinous crime under Fremen law, threatening not simply the survival of the individual but thai of the tribe and, ultimately, Fremen as a people. For them it was adenb alaguil gitfd quibir, "the first and greatest sin." The gravity of the crime was directly proportional to the scarcity of moisture on the harsh world of Arrakis. This scarcity can easily be underestimated. To appreciate it is to understand what Jacurutu represented in Fremen myth: the ultimate treachery. The manifold responses to water scarcity among the Fremen is well-documented. The conservation of water was at the core of Fremen culture-central to their laws, rituals, social obligations and religious aspirations. No aspect of Fremen life was unaffected by it. For Fremen, water was Life. By their crimes, the Iduah of Jacurutu violated Fremen values on every pertinent level, The gravity of the transgression was, of course, deepened by the fact that the Iduali were Fremen as well. 354 According to legend, Jacurutu was assaulted and its people annihilated by a general alliance of Piemen tnbes Thereafter, the Iduali were referred to as the Cast Out and the sietch declared tabu It is undoubtedly a measure of Fremen psychology that only the inhabitants of Jacurutu were destroyed, while die wmdtrap and other devices used for the collection and storage of water were left intact During the power struggle preceding the accession of Leto II to the Imperial throne, it became apparent that Jacurutu was no myth, and that the "water insects" had not been completely wiped out Although dispersed, remnants of the Iduali regrouped after many years and became smuggler? of melange for off-world shipment They, with die false pride of die justly persecuted, swore vengeance on any who were not among the Cast Out Those hapless enough to discover their sanctuaries were murdered and their bodies sent to the deathstill These sanctuaries were in two places Jacurutu itself, then known as Fondak-a smuggler place of uncertain location, and Shuloch Both enjoyed comparative safety-Jacurutu because it was tabu, Shuloch because, as another sietch mentioned only m story, its actual existence was discredited and its location unknown Jacurutu emerged prominently from myth to contemporary history in two respects during the final days of the Imperial Regency It was discovered that Maud'Dib.
