Hades III

Hades III is a smog planet in the [Hades system](https://robertsspaceindustries.com/galactapedia/article/RAX3mnkp8v-hades-system). Its high-pressure, toxic atmosphere covers a landscape riddled with impact craters and the scant remains of abandoned cities. Due to dangerous conditions, researchers have only been able to make a few expeditions to explore and document these ruins. Planetary scans show that while nearly all of these sites have been eroded away, many more ruins lie buried beneath the surface.
