Octagon Society: Established in 342, the Octagon Society was the first major distressed spacefarer assistance operation in the Domain of Deneb. It thrived on public contributions and some tax revenues for 150 years. It failed in the late 400s when scandals emerged over the quality of shelter construction and disposition of certain funds. The society was dissolved in 499 and its assets sold at auction. Society shelters were generally of an octagonal shape. The society established large hostels on major worlds, and placed smaller weather shelters on frontier or unsettled planets. Some were 40 parsecs beyond Imperial borders. The characteristic octagon shaped buildings are still visible on various worlds, although none are still in use as shelters. Off-dirt Rank: Mercenary jargon for the courtesy title major, applied to non-naval captains when aboard starships, to avoid confusion with the starship captain. Ojehshodu: Minor race on Neghu Oug/The Narrows (Corridor 2804). Omega Point: The ultimate state of the Universe. Cold freeze or contraction into a hot supermass? One Imperium Movement: Adherents believe that all peoples of both previous Imperiums should be united in one massive Imperium, including the Solomani Sphere and the coreward extents of the First Imperium. The movement has a long history, dating from shortly before the verification of the Solomani Hypothesis. Oniochalasia: buying as a means of mental relaxation. Onnesium: Rare element, atomic number 118, mildly radioactive and dangerous, which has been proved to be a viable room-temperature superconductor. Onnesium is normally found as small, silvery spheres embedded within meteoric nickel-iron. It is created within supernovae, plated onto asteroidal surfaces, and eventually can be discovered in free-floating asteroids or in impact craters on planetary surfaces. Recent discoveries of onnesium in the Gavza system (Reavers Deep) have suggested that a supernova at Scotian Deep 0308 may have spread onnesium deposits to several nearby systems in the Scotian Deep subsector. [FT2] Opaldew: tropical fruit. Opheides: Minor race on Orphee/New Islands (Reft 1429). Descended from grazer stock. Orbital City: A closed-cycle orbital station with a permanent population in the thousands. Possible at tech level 9. Orbital settlement: An open-cycle orbital station with a permanent population in the hundreds. Possible at tech level 8. Ormine: Minor race on a world in Akhlare subsector (Dark Nebula). Otrai: minor human race & culture. Ourrghfoengaeknokskugvorrgh: "Church of the Chosen Ones." Outrim Void: Colloquial name for the region rimward of the Spinward Marches. It consists of many independent worlds, small empires, and Aslan colonies. The Imperium's civilian population, who know little about it, regard it with suspicion. Corsairs and persons escaping Imperial justice find it a natural haven. Historians believe many Outrim worlds were settled during the Rule of Man. Some worlds maintain links to the Imperium or the Zhodani Consulate. Other worlds have been isolated from outside contact since they were first settled. Oynprith: Common language of the Droyne.
