The surface of Eostremonath, before terraforming; the surfaces waters of this world held primitive anaerobic life

A world that supports extensive microbial biomes in its oceans and other regions, but which has not yet seen the development of more complicated forms of life. The atmosphere often remains largely carbon dioxide and nitrogen in nature, although it may be in the process of turning over into a clearer, oxygen atmosphere as life makes the transition from anaerobic forms to aerobic forms. Example: Eostremonath (preterraforming).
