Antirumgon is a small rock and ice planet, with a trace atmosphere of methane and ethane. The frozen surface is mainly composed of carbon with deposits of calcium. Deposits of cobalt may also be found on its surface. Antirumgon has been used as a crude anchorage for Terminus pirates for many years. The shells of temporary dwellings blasted by Alliance frigate patrols dot the surface. But always, the pirates return to ground their ships' drive charges, chip out some water ice, and trade slaves and stories.
