Here is my elevator pitch for the Expert Outreach setting. The game will use an adapted version of the Expert Nova rules.
The Zakharr, alien invaders, crushed and chained humanity, and exploited and wrecked Terra for almost a century. But suddenly their empire crumbled as a strange plague killed them all. Who arranged this fortunate calamity and why? Nobody knows.
It’s now AD 2203. Forty years have passed since Terra’s liberation. We humans are busy building a new future in the ruins of the past, surrounded by the remnants of an advanced alien society.
Your mission – if you choose to accept it – is to participate in the rebuilding of our civilization by exploring interstellar space, by unravelling the mysteries of the Zakharr, by liberating fellow humans enslaved on distant worlds, and by thwarting the hostile schemes of alien species. You will be a small actor in a huge arena. No one can do everything, but everyone can do something to save our species from extinction.
But keep in mind, the galaxy is a dangerous place.
