A run-down planet once bustling with culture and life, all paved over in years past in favour of rapid expansion and cheap architecture. It's grey and dull, with worse weather from climate change. The whole planet used to be seen as almost a tourist destination, but that was centuries ago, when the place was sunny and had a speck of clear water.
Kinndra doesn't seem to value Ethos beyond its ability to rapidly turn around whatever military equipment she needs, shaking up factories at a rapid pace to keep up with extreme and fickle demands. Most people on Ethos either work in the factories or work supplying the factory workers.
Of course, there are still the small pockets of resistance, often deep under layers of industry and hidden away in the pockets rumoured to contain the poor bastard souls who refused to kneel so many years ago when Kinndra took the planet initially. Or maybe the groaning is just the pipes.
