There were no other prisoners in the holding cells you were kept in overnight, though you were within talking distance.
The next day, you are led out to the prison ship- an ugly grey mass, made uglier still by the absurd shield bolted onto its front; the vast ram that will take the brunt of the Void particles when the ship emerges from hyperspace.
There, you are taken into the prisoners' hold, and strapped into seats there. The hold is let, dimly, with a red light, and the seats are very secure. There are about two dozen other prisoners.
