So, I got this idea from Star Wars: The old republic, from where I won't say
We will all be playing people of different classes, Sith acolytes, Officers, diplomats, slaves, merchants invited to join a mysterious benefactor on a ship.
Mid through a hyperspace jump, the ship stops, power goes out, and the cabins lock. Only the communication with the other cabins is still up. There's 8 equally sized cabins, two persons in each, a man and a woman. The cabins are equipped with cabinets containing food enough to survive for a few weeks, and beds comfortable enough to sleep soundly in.
