Pallas

Pallas was a planet in orbit of star Helios Beta-system. The largest uninhabitable planet in the Cyrannus Sector, Pallas had an inclined orbit between that of Virgon and Leonis.

Although it has been speculated that Pallas was once able to support life, the planet is now dead and barren. At some point in history an unknown event or series of events lead to the end tectonic activity, presumably the loss of a magnetic field, and subsequent loss of most of the atmosphere to solar wind.

Despite this, Pallas is still has a significant population and is home to a number of colonies and a presumably important military research station. The planet was significant enough to warrant a number of attempts to terraform it, all of which had failed.
