Inon III

Inon III is a radioactive planet in the Inon system, twin planet to Inon II. However, the two planets could not be more different. Whereas Inon II is a vast cityscape at the pinnacle of League Civilisation, Inon III is a husk of radioactive waste with no life whatsoever and no potential for terraforming. Even the Composer, in its near-infinite terraforming power, is still not enough to penetrate the planet's acid-infused atmosphere.

Many trading ships and even military deployments have run afoul of Inon III's natural defence - a massive asteroid field that encircles the planet. The combination of this field and the radioactive atmosphere of Inon III makes some League scientists think that there was once a civilisation on the planet that utterly destroyed the ecosystem and were then destroyed, in a similar situation to Urrrrrrrr. Whether or not this is true, however, can never be determined.
