UX-9 II is a planet with attractive features such as plenty of surface water and excellent temperatures; however, it is also a high gravity world with a very dense atmosphere. Currently the planet only has prokaryotic microbial life, but it could easily support some types of familiar plants and eventually animals. Gravitational forces from its second sun result in heavy volcanism and earthquakes during certain time periods and extreme tides.
This system has been scanned and charted by the Yamatai Star Empire and the YSE has set up an emergency outpost on the planet. The Yamatai Star Empire placed orbital communications networks of Emrys Satellites around all of the terrestrial planets in YE 36.
