Noombars civilization originates from the giant star system consisting of several dozens of planets with liquid-gaseous surfaces. As a result of terraforming, the planets were covered with fragile porous hydrochloric lumps grown by chemical reactions, which like icebergs, were moving by a viscous surface of the planet, sometimes colliding with one another. These islands were the places of construction and urban habitat of Noombars race. Only a tiny width a few hundred meters layer of the planet’s atmosphere, filled with air-like gas was suitable for human life and building of a sustainable society. Nation of Noombars eventually adapted and learned to use suitable climate zones for creation of numerous sities and communities, which were centers of scientific and technological development of the whole nation. However, a great disparity in welfare and overpopulation of citizens led to a political mode in which the poor citizens were expelled from the favorable climate zone - either rising above or descending below. Technological progress allowed to adapt to the hostile environment and settlements continued to grow beyond a favorable climatic zone.
People of lower and upper zones exchanged gathered resources and collected goods for equipment and weapons. Developed protection systems and weapons exterminated those who tried to return to a favorable climate zone. For the generation of rather peaceful development interrupted by periods of revolutions and rebellions was formed a special class of mid-residents. Median-residents grant to their heirs the privileged civilian status and elect governors from among themselves. Median-residents have the power to control technologies and hire the soldiers from the upper and lower zones, who hardened in endless struggle for survival, to protect their borders hoping to get into a zone of favorable microclimate as a reward for a lifetime military service. The ruling elite of mid-residents are quite coddled hedonists living in comfort divorced from reality while the inhabitants of the upper and lower zones are incredibly persistent and deadly warriors, acquiring glory to their motherland throughout the universe. The high command of the army consisting mainly of good-natured representatives of the unfavorable zones determine the actual policy of the nation although they are not formally mid-residents.
