The rise of the Third Imperium did not go unchallenged. For centuries the inhabitants of Paradisio warred with the expanding Anwn Imperium- Paradisio gaining the upper hand again and again, but always failing to land the killing blow upon their rivals.
Tiring of what seemed a never-ending conflict, the Anwnites destroyed the Paradisian navy and planet-bombed their home planet into a final and lasting oblivion. What was once a lush garden planet is now a harsh wasteland devastated by the long term effects of radioactive, biological and chemical pollution.
Paradisio- no longer a paradise in any sense of word- became known by the name given to them by their enemies: Nemesis.
The former Paradisan supermen and women now live in domed cities, surviving on food grown through hydroponic farming and resource mining done by those brave, strong, and desperate enough to leave the relative safety of the domes.
The domes themselves are like city states- independent and ruled by local brahmins who trace their lineage back to the glory days of their civilization.
Nemesis is an ancient system, and was likely an early colony of the early diaspora from the mythical home planet of Shenjou. As such, there is much to be found in the way of ancient artifacts on this ruined and hostile system - perhaps even something might be found that can lead back to technology that is now lost...
