Hmm, well, I would say that while the Princes are currently the highest powers in Hell the Arena Master holds authority over the Colosseum and it's going-ons. Though the slaves themselves are to be trained for the Princes by the Slave Masters, so technically the Princes will have their say as to which slave they have their eye on.<br/><br/>At the moment, once slaves have finished their battles and are returned to their cages below the arena, they will meet with their assigned Slave Masters. However, Princes may also take this chance to go and pay them a visit. This would probably be a good time for Slave Masters to figure out which Prince they want to cozy up to most. =)
