LV-426 'ACHERON': that's the terraforming hell-hole of a planet we call home. A colony of scientists and hard working people, making better worlds.
We are intergalactic circus people, performing for the enjoyment of the good colonists, and the other races we meet in our travels.
We left Acheron some time ago, and for some reason, we haven't been able to get in touch with our home planet in recent times. We can't figure this out: all communication has just broken down.
