The story
Lone Star is a mining station. It travels to asteroid fields far from home, mines them for years and brings the metal back. You're its flight engineer, the one who keeps its ships flying.
On the way home from a long job, the station's jump went wrong. It came out in the Shoals, a star system none of the crew had ever heard of, and a cartel called the Skarn was waiting. They wrecked the station, tore out the crystal that powers its jump drive and left.
Most of the crew didn't survive. The ones who did are sealed in shelters with the power out. The only ship still able to fly is the small mining ship you'd been rebuilding in a back bay, so that's where you start.
