Hunter of Worlds
C. J. Cherryh
 In the story, a ship belonging to a terrifyingly dominant space-faring race, the iduve, arrives at a space station. They demand that a particular station resident, a blue-skinned Kallian, be sent to their ship and all record of him be erased. No defiance is possible or the space station will be destroyed. The human-like Kallian is handed over to the iduve who mind-link him to two other human prisoners, forcing him to service his captors on three levels.
