Halyme is a "post-garden" world that once enjoyed an Earth-like oxygen-nitrogen atmosphere. It is still blessed with plentiful water, but a generally cold climate (and extreme seasonal shifts, courtesy of a 38-degree axiat tilt).
Helyma is thought to be the homeworld of the arthenn, a spacefaring species which disappeared approximately 300,000 years ago. Precisely what happened to Helyme is still under debate. It appears a global extinction occurred, wiping out all native animal life forms more complex than zooplankton. Plant forms were not affected, but the lack of oxygen-breathing life caused oxygenation of the atmosphere. Plant life was reduced after lightning storms ignited global wildfires.
The leading theory for Helyme's devastation is an out-of-control biological weapon. For this reason, landing is strictly prohibited. The corporations of Illium have emplaced a network of quarantine satellites to dissuade would-be looters from landing in the crumbling cities.
