Gyomar has an exotic, corrosive, or insidious atmosphere with a small percentage of liquid, but not water, on the surface. The system has a population over a hundred million, but not yet at a billion sophonts. It is a Human dominated Non-Aligned world in the Cronor Subsector of Spinward Marches Sector. This is the homeworld of the Tethmari, a Minor Race. They are 100% of the world's population.

Astrography & Planetology[edit]

Despite Gyomar’s -120 ° C temperature and tremendous atmospheric pressure, the world has a rich biosphere populated by ammonia-based life forms.
