└ Hades system
└─ Orbiting Hades (star)
Hades II is a terrestrial rocky planet, once inhabitated by the Hadesians.
The planet still has a thin atmosphere left. Environmental suits must be worn all the time, due to the amount of volcanic ash and strong winds.
The planet was once settled on the surface. Many of the planet's ruins are sealed underneath due to the ash that spews from the volcanoes that dot the surface. Many different surveys have been performed to both get into the ruins and to analyse them for safekeeping, but because of the harsh environment (swirling storms, lightning strikes, tornadoes etc), it's very difficult to conduct a stately, slow and correct archaeological survey.
Deposits of Kherium, a mineral prized by the Xi'an for use in their armor plating, have been discovered on Hades II, although, due to the archaeological value of the system, no corporate mining campaign has ever been authorized.
